CIRCUITCO BB-BONE-BBPR-01 电路板, BEAGLEBONE, BEBOPR子板
The is a BeBoPr provides all the necessary I/O to control a Mendel/Reprap 3D printer. Onboard 3 analogue inputs optimized for thermistors, 6 digital inputs for limit switches, 3 high power PWM outputs for heaters or fan and 4 axis stepper motor interface for either external drivers. The "hard "real-time control runs on dedicated coprocessor that is part of the AM3359 on the BeagleBone. The "soft" real-time control runs on the ARM processor under Linux.
