Re: Interfacing to the new HE280 accelerometer...

After some feedback from mhackney, I've redesigned the PCB for the next revision. The major difference is that the board now has better mounting, and better IO for a final unit, and support for SPI communication between the accelerometer and chip has been ditched as it wasn't used, as has configurab...
