OpEncoder is an open source magnetic encoder hardware designed for robotics and motion control applications. It is based on AEAT-8800 IC from Broadcomm. Some features are:
-16-bit resolution (0,0054 degrees ?!)
-PWM output mode
-24 mA current consumption during normal operation conditions
-2,5mm x 2,5mm PCB size
Design and production files of OpEncoder Lite V.1.0 are attached to the project, also they could be found at github page of project. The lite version is intended for size-critical applications and enviroments.
