System-on-Module in credit card format

January 16, 2014 // By Julien Happich
The credit card-sized M-9G45-A board PC offered by independent German distributor acceed features an ATMEL 400 MHz processor and is equipped with 128 MB DDR2 random access memory (DRAM) as well as NAND flash memory with 128 MB.

The memory can be extended via an SD interface for memory cards with up to 32 GB. Measuring only 80×50mm, the board PC is easy to fit into the smallest housings for space-critical applications in industrial and medical technology.

The new Linux-based M-9G45-A comes with a variety of interfaces: 4 × UART, 1 × USB-2.0 (480 MBit/s), 1 × I²C, 1 × I²S, 1 × SPI, 1 × Ethernet and an interface for audio output. With its  TTL/LCD monitor interface incorporating brightness control, the M-9G45-A supports TFT monitors up to a resolution of 1280×860 pixels. Touchscreens can also be connected. Fifteen GPIOs offer adequate flexibility for input and output programming. It consumes less than 2 watts' electricity.

The pre-installed operating system Linux 2.6.38 is supplemented by the GCC/GLIBC/GNU tool chains and also enables beginners to develop their own software. The Web-based administration works well using the pre-installed program "webmin". Should the application software work uncontrolled at any point in time, the integrated watchdog timer independently ensures a safe system reboot.
