What do you think of an Atmega + Raspberry Pi expansionboard


I have been working on a project for a couple of month now and are soon ready to send this to production. It is a I/O board with 4 relays, 8 digital inputs, 4 RS232 and 1 RS422/485. All inputs are ESD and EMI protected.

The main purpuse of this board is to make it easier for everyone to develope some homeautomationproducts with Arduino and Raspberry Pi.
