The DIO (Digital IO) brick for my brick-o-lage project is already finished. I designed schematic and PCB using fritzing . Also I ordered the PCBs from fritzing FAB (and they turned out great). For the firmware I used my own libemb as a basis.

- Uses a MSP430G2553 from TI
- Runs custom firmware
- Connects to master brick through I2C
- 4 digital outputs
- 4 digital inputs

- Serial RX/TX for debugging
