|Interface Board for Beagle Bone
||Design an Analog Input board for Beagle Bone Black CPU module
The board should sit on top of the Beagle Bone CPU and have 4 analog inputs, (16bit each, Resistor selectable to current/voltage input) and 4 digital inputs (up to 100 khz counters). Beagle Bone CPU module interface is via SPI bus and I2C.
The schematics design and board layout for this board must be kept confidential.
