Description

The CM-T3517 is a small Computer-on-Module board designed to serve as a building block in embedded applications. The CM-T3517 includes all the peripherals required to run operating systems such as Linux and Windows CE. Ready packages for these operating systems are available from CompuLab.

The small size and low power consumption of the CM-T3517 allow its integration into portable and space-constrained designs, while its low price makes it an ideal selection for cost-sensitive applications.

The CM-T3517 features Texas Instruments’ Sitara AM3517/05 system-on-chip based on the advanced Cortex-A8 ARM CPU with a PowerVR SGX GPU providing 2D / 3D graphics acceleration. For embedded applications, the CM-T3517 provides a general-purpose local bus, 100Mbit Ethernet, CAN bus, serial ports, I/O lines and other essential functions, while the integrated WLAN and Bluetooth interfaces implement industry standard wireless connectivity.

The standardized CAMI ("CompuLab's Aggregated Module Interface") connectors of the CM-T3517 module allow interchangeability with other Computer-On-Module's available from CompuLab, enabling the flexibility required by a dynamic market in which application requirements can change rapidly.
