Servo reverse engineering
Interact
Posts: 79
So I finished my motor controller project to interface to stamps, using back EMF , serial communication , auto baud, ramp speed, auto calibration, etc. etc. Really excited about how well it works. Then I got to thinking how nice it would be to just jam the chip into the gear motor housing where the old servo board was. (servos with electronics striped out as gear motors). I'm using a bridge driver chip that wouldn't fit in the housing but the driver circutry on the original board is very compact.
·Then two ideas came to mind:
1: Reverse engineer the driver parts on the board and make a new board with my chip (tiny) in place of the chip that came with the servo. This could also lead to a serial servo, as well as the serial gear motor.
2: Figure out what the controller chip is on the existing board and just ISP the existing chip with my own software. That would be really nice but my guess is that the mystery chip is some sort of proprietary chip.
It’s been a while (long while) since I was a working EE, and I am not good at identifying surface mount components. Any way to tell what is on this board??
