On top of our PCB we have a Gumstix plugged on a Tobi expansion board. The Tobi is connected to our PCB thanks to a 40 pins header, used for communication (UART) and to handle the reset of the STM32. Here are some specs:
Gumstix Overo FE COM:
- OMAP 3530 (ARM Cortex-A8 CPU), 600MHz
- 256MB RAM
- micro SD card slot
A video camera (Caspa FS) is also on the Gumstix, able to take pictures of the ground.
We installed Ubuntu on it.
