This I/O board gives your Bioloid robot the ability to connect to almost any analog (0-5 volt) sensor. It includes 6 analog inputs (10 bit resolution on each). It also includes four general digital I/O pins, and can drive one or two DC motors using either locked anti-phase or sign magnitude PWM.
The board includes a 5 volt regulator and a 3.3 volt regulator, and will work at either voltage.
This I/O board is a Bioloid bus device, and is fully compatible with the CM-5 controller. Each board has an ID (defaults to 122), and can understand most of the same commands that stock Bioloid devices can understand (READ_DATA, WRITE_DATA, etc).
Board dimensions are 2" x 2" (50.8 mm x 50.8 mm), and it includes a hole in each corner than can take a #4-40 or 3mm machine screw.
