(CalAmp)

Unlike conventional battery-powered asset trackers that eventually require battery replacement or recharging, the TTU-2900MB uses solar regenerative telematics to replenish its internal battery whenever sufficient light is available. Its large battery provides reserve capacity for operation during extended periods of low light, making the TTU-2900MB particularly well suited for long-term unattended deployments. (CalAmp)

Solar Regenerative Telematics

The defining feature of the TTU-2900MB is its integrated high-capacity solar panel.

CalAmp designed the unit to harvest solar energy and maintain its internal rechargeable battery, reducing dependence on external asset power. The platform combines the solar charging system with a high-capacity internal battery for operation during extended low-light conditions. (CalAmp)

This architecture is particularly valuable for assets such as trailers, containers and equipment that may remain parked, disconnected or otherwise without reliable vehicle power for long periods.

For fleet operators, solar regeneration can reduce the operational burden associated with retrieving devices for routine charging or battery replacement.

6.2 Ah Rechargeable Lithium-Ion Battery

The TTU-2900MB incorporates a substantial 6.2 Ah rechargeable lithium-ion battery pack. (CalAmp)

CalAmp specifies:

• Battery capacity: 6.2 Ah

• Battery technology: Lithium-Ion

• Charging temperature: -10°C to +50°C

The combination of the large rechargeable battery and solar panel enables the tracker to maintain reserve energy for periods when the asset is indoors, shaded, covered, or experiencing prolonged low-light conditions. (CalAmp)

Global LTE Cat-M1 Connectivity

The TTU-2900MB provides LTE Cat-M1 cellular connectivity designed for wide-area IoT and asset-tracking applications.

CalAmp specifies the global variant across LTE bands corresponding to:

B1 / B2 / B3 / B4 / B5 / B8 / B12 / B13 / B18 / B19 / B20 / B25 / B26 / B28 / B39. (CalAmp)

CalAmp describes the cellular architecture as globally deployable and positions LTE Cat-M within the massive-machine-type-communications evolution of 5G standards. (CalAmp)

2G GSM/GPRS Fallback

In addition to LTE Cat-M1, the global TTU-2900MB supports:

GSM/GPRS 850 / 900 / 1800 / 1900 MHz. (CalAmp)

This provides an additional connectivity option in regions where compatible 2G networks remain operational.

Supported data communications include:

J1939 Heavy-Duty Vehicle Data

The TTU-2900MB provides CAN connectivity supporting SAE J1939. (CalAmp)

J1939 is widely used in commercial trucks, heavy equipment and other heavy-duty vehicle platforms, making the TTU-2900MB useful in applications where the tracker needs to interface with compatible vehicle or equipment data networks.

This differentiates the TTU-2900MB from simpler solar trackers that provide location information but have little or no capability to interact with the host asset's electronic systems.

TrailerCAN Connectivity

CalAmp also specifically identifies TrailerCAN support as part of the TTU-2900MB's vehicle-bus architecture. (CalAmp)

TrailerCAN provides an important integration path for advanced smart-trailer applications where compatible trailer systems and sensors need to communicate with the telematics gateway.

Combined with cellular communications, GNSS, BLE and wired I/O, CAN connectivity allows the TTU-2900MB to operate as a smart-trailer telematics gateway, rather than simply a solar-powered location beacon.

Bluetooth Low Energy 5.0

The TTU-2900MB incorporates Bluetooth 5.0 for short-range wireless connectivity. CalAmp specifically highlights Bluetooth as part of the platform's sensor-integration capabilities. (CalAmp)

BLE can provide a wireless connection between the tracker and compatible nearby sensors or peripherals, reducing the need for every sensor to be physically wired to the tracker.

This architecture is especially valuable for sensor-rich trailer and industrial asset applications where information from multiple points on an asset may need to be consolidated and transmitted through a single cellular gateway.

Comprehensive Sensor Integration

CalAmp specifically designed the TTU-2900MB around rich connectivity for sensor integration.

The platform combines:

• Bluetooth wireless connectivity

• CAN bus

• TrailerCAN

• Digital inputs

• Analog inputs

• Digital outputs

• TTL serial

• RS-232 serial

• 1-Wire connectivity (CalAmp)

This combination enables the TTU-2900MB to collect information from a much broader range of compatible equipment than a conventional standalone GPS tracker.

Three Configurable Digital Inputs

The TTU-2900MB provides three configurable digital inputs with selectable high- or low-bias operation across 0–30 VDC. (CalAmp)

These inputs can be used in appropriately engineered installations to monitor compatible switches, sensors and equipment states.

A separate fixed-bias ignition input is also provided. (CalAmp)

Together, these interfaces allow telematics applications to associate location and movement information with the operational state of the connected asset.

Dual Digital Outputs

The tracker provides two open-collector relay-driver digital outputs, each rated at 150 mA. (CalAmp)

These outputs provide a mechanism for appropriately designed telematics applications to interact with compatible external relays or peripheral equipment.

Dual Analog Inputs

The TTU-2900MB provides two external ADC analog inputs. (CalAmp)

Analog inputs allow the gateway to monitor variable electrical signals rather than being limited to simple digital on/off conditions.

This can be useful for sensor-rich applications where compatible equipment produces a voltage corresponding to a measured condition.

1-Wire® Driver ID & Temperature Sensing

A dedicated 1-Wire® interface provides another peripheral integration path.

CalAmp specifically identifies the interface for:

• Driver identification

• Temperature sensing (CalAmp)

Temperature sensing can be particularly useful for refrigerated trailers, temperature-sensitive cargo and industrial equipment, while identification peripherals can support specialized vehicle or equipment workflows.

TTL Serial Connectivity

The TTU-2900MB provides a dedicated TTL serial port for compatible external equipment. (CalAmp)

This provides another method of exchanging data between the telematics gateway and specialized sensors, controllers or peripheral devices.

RS-232 Serial Connectivity

In addition to TTL serial, the TTU-2900MB includes a dedicated RS-232 port. (CalAmp)

RS-232 is particularly valuable in commercial and industrial applications because many established pieces of fleet, sensor and equipment hardware use conventional serial communications.

Providing both TTL and RS-232 significantly expands the range of peripheral-integration possibilities.

Switched Peripheral Power

The TTU-2900MB provides:

• 1 switched VCC_SYS output — 3.5 to 4.2 V

• 1 switched 3.3 V output (CalAmp)

These switched power resources provide additional flexibility when integrating compatible sensors and peripherals.

Built-In Three-Axis Accelerometer

The TTU-2900MB incorporates a built-in triple-axis accelerometer.

CalAmp identifies accelerometer functionality for:

• Driver behavior

• Impact detection

• Motion sensing

• Tilt detection (CalAmp)

Motion sensing is especially valuable in a solar asset tracker because the device can distinguish between a stationary asset and one that has begun moving.

This information can be incorporated into intelligent reporting strategies so the tracker can conserve energy while an asset is stationary and respond appropriately when meaningful activity occurs.

Multi-Function Push Button & LED

The TTU-2900MB incorporates a multi-function push-button switch with an LED indicator. (CalAmp)

This provides a local interface for supported installation, service or operating functions and gives technicians immediate visual feedback from the device.

PEG™ Programmable Edge Intelligence

The TTU-2900MB incorporates CalAmp PEG™ edge intelligence.

CalAmp describes PEG as enabling customers to update device functionality or develop new applications at the edge. (CalAmp)

Edge processing allows supported conditions to be evaluated locally by the tracker rather than requiring every event to be transmitted to and processed by a remote server.

Application logic can incorporate information from the TTU-2900MB's GNSS position, ignition input, digital and analog inputs, motion sensor, CAN bus and connected peripherals.

For solar-powered applications, local event processing can be especially valuable because intelligent reporting can help balance asset visibility, cellular activity and power consumption.

Low-Power Asset Operation

Despite its extensive communications and sensor capabilities, the TTU-2900MB provides low-power operating modes designed for long-term asset deployments.

CalAmp specifies typical power consumption of:

• 400 µA at 12 V — deep sleep

• 15 mA at 12 V — radio-active sleep

• 60 mA at 12 V — active GPS tracking with cellular enabled (CalAmp)

Combined with the 6.2 Ah battery and integrated solar panel, these low-power operating states are central to the TTU-2900MB's ability to support extended unattended deployments.

12/24-Volt External Power Support

Although solar power is a defining feature, the TTU-2900MB can also operate from conventional vehicle or equipment electrical systems.

CalAmp specifies support for 12/24 VDC systems, with:

• 9–30 VDC startup and normal operation

• 7–32 VDC momentary operation (CalAmp)

This allows the TTU-2900MB to be used on assets where external power is available while retaining solar charging and substantial internal battery capacity.

Rugged IP67 Weatherproof Construction

The TTU-2900MB carries an IP67 ingress-protection rating and is specifically described by CalAmp as a weatherproof solar-powered tracker for extreme environments. (CalAmp)

Its sealed construction provides protection appropriate for outdoor asset installations exposed to dust and water.

This is particularly important for trailers, containers, construction equipment and industrial assets, where a telematics unit may spend its entire service life mounted outside a protected vehicle cabin.

Rugged Shock & Vibration Performance

CalAmp specifies shock and vibration performance referenced to:

• U.S. Military Standard 202G

• SAE J1455

ESD performance is specified to:

• IEC 61000-4-2 — 4 kV test level (CalAmp)

These specifications complement the IP67 enclosure and support deployment in demanding transportation and industrial environments.

Wide Operating Temperature Range

CalAmp specifies:

• -30°C to +60°C when connected to primary power

• -20°C to +60°C while operating from the internal battery

• -30°C to +45°C for up to six months for long-term battery storage

• 75% relative humidity at 50°C, non-condensing (CalAmp)

The internal battery itself can charge over a specified range of -10°C to +50°C. (CalAmp)

Internal Cellular, GNSS & BLE Antennas

The TTU-2900MB incorporates all primary wireless antennas internally:

• Internal cellular antenna

• Internal GNSS antenna

• Internal BLE antenna (CalAmp)

This self-contained antenna architecture eliminates the need to route separate antenna cables across the asset and helps preserve the simplicity and environmental integrity of the installation.

Heavy-Duty Round Connectors

The TTU-2900MB uses two dedicated round connectors for power and peripheral integration:

• 1 × 12-pin round connector

• 1 × 14-pin round connector (CalAmp)

CalAmp also offers optional harnesses for installation.

The use of separate multi-pin connectors reflects the TTU-2900MB's substantial I/O and sensor-integration capabilities.

External Nano-SIM Access

Unlike many sealed telematics devices with an internal SIM, the TTU-2900MB provides external 4FF Nano-SIM access. (CalAmp)

This can simplify SIM installation and service when deploying the device with different supported cellular connectivity arrangements.

Large Solar Enclosure

The TTU-2900MB's integrated solar panel and substantial 6.2 Ah battery result in a larger enclosure than conventional GPS asset trackers.

CalAmp specifies dimensions of:

18.2 × 5.0 × 1.9 inches
463 × 128 × 48 mm

Weight is:

38 oz / 1,084 g / 2.375 lb with the 6 Ah-class battery. (CalAmp)

For your DCS Shopify catalog, I would therefore use 2.375 lb (38 oz / 1.084 kg) as the product weight for the TTU-2900MB itself, before adding any separate packaging or accessory weight.

CalAmp Telematics Cloud Integration

The TTU-2900MB supports CalAmp Telematics Cloud, allowing remote assets to connect with vertical applications and third-party services.

CalAmp specifies that device data can be streamed through RESTful APIs. (CalAmp)

This enables TTU-2900MB information to become part of proprietary asset-management, trailer-management, fleet-management, reporting, analytics and enterprise IoT systems.

The cloud service is subscription-enabled. (CalAmp)

CalAmp iOn Fleet Management

The TTU-2900MB also supports CalAmp iOn fleet-management software as a subscription-enabled service. (CalAmp)

This gives organizations the option to combine the hardware with CalAmp's software ecosystem or integrate device data into another compatible platform through the available API infrastructure.
