The electronic is based on a PIC32 from Microchip.
I made all the schematic and the layout on Altium and then, I made the board on BatchPCB which has changed to OSH Park. The quality is very good and the price quite low (around 50$ for this board)
The mother board is composed of :
- Audio module SOMO14D
- Accelerometer LIS2L02AS4
- Bluetooth module Free2move
- An eeprom
And how it looks like both boards connected :
