BeagleBone Black
In contrast to Raspberry Pi :
- better I/O capabilities with 7 channel 200kHz 12-bit ADC, 8 PWMs, 4 UARTs, quadrature encoder hardware
- don't have to buy additional components to connect up many more sensors and actuators
- large number of PWM channels on the Bones make them better for motors
- better real-time control with two 200MHz, 32-bit RISC programmable real-time units (PRUs)
- approximately 20 books available for texts, reference and projects
