Ruediger F. LoeckenhoffI am presently writing a detailled description of the board and I realized how usefull the second I2C port of the ATMEGA328pb may be. It allows you to turn the whole board into an I2C slave for a Raspberry Pi. You can controll the motors of a two wheeled robot (digger) and set servo positions through I2C. On the other hand, the board can constantly read the compass chips and RTC and provide the results in registers for the RasPi to read. I am getting more and more confident that the board can be a hit!
Make it an I2C device for RasPi robotics!
