Rugged Android fleet computer offers 3G, GPS, CANbus

Apr 15, 2014 — by Eric Brown 1,764 views

Micronet announced a rugged touchscreen fleet computer that runs Android 4.x on a TI Sitara AM3715 SoC, and features optional GSM 3.5G, GPS, and CANbus.

Micronet’s A-317 fleet computer updates the A-307 device that shipped last August. Both of these software-compatible devices are low-end complements to the long-haul oriented CE500 series fleet computers, says Micronet, a subsidiary of Micronet Enertec Technologies (MICT). The devices support fleet management and mobile resource management (MRM) applications, says Micronet.

The A-317 dispenses with some of the OEM-optional features of the A-307 and instead offers both a standard model, as well as an “all-in-one” model that incorporates many of those options. The base model is designed to interface with third party telematics units (AVL boxes). The all-in-one model adds GSM 3.5G and EVDO cellular modems, as well as GPS and a pair of CANBus interfaces.

Both of these “fix-mount” vehicle computers are also smaller, and almost half as thick, as the earlier device. They’re also significantly lighter, weighing in at 498 grams. Space savings were found by removing the buttons that previously flanked the screen on either side. A backlit rubber tactile keypad and mono speaker sit to the right of the screen, and a microphone is also available.

The A-317 uses the same ARM Cortex-A8-based Sitara AM3715 SoC from Texas Instruments provided by the A-307, but RAM has been doubled to 512MB. Flash memory stays the same at 512MB, and as before, an SD slot is available for expansion.


The A-317 provides the same 7-inch, 800 x 480, 4-wire resistive touchscreen with multi-level backlight. A multi-touch capacitive screen is said to be optional, and the previously optional light sensor is now standard.

The once optional Ethernet port is gone, but you get WiFi and Bluetooth as standard features. Other I/O is similar, including a pair of USB 2.0 host ports, a USB 2.0 OTG port, and a pair of serial ports. You also get DIO and analog inputs as standard features. As before, there’s IP54 compliant ingress protection, and J1455 compliant vibration and shock resistance. The operating range is said to be -20 to 70°C.

The A-317 supports Android 4.0 (“Ice Cream Sandwich”), and is enhanced by Micronet’s in-house implementations of telematics-specific features and functions, says the company. A software and hardware development tool kit is also said to be available.

The device is available with Micronet GSD, a cloud-based advanced remote device management system. GSD equips MRM service providers and end user fleet customers with MDM technology used for corporate policy compliance, remote device access for online training, support and trouble-shooting; and over-the-air (OTA) functionality for secure upgrades. Micronet GSD can be used with all Micronet Android based products, as well as with any other standard Android based mobile devices, says Micronet.

  1. Ramilies says:


    What do surprise me a little, despite the quality of the sitara family, is the use of a cortex A8 core and the limitation to 512 mb for such device with the risk of the same level of latencies as the ones which are encountered on low level tablet embedding the same family of processors.
