Talk:Pololu Electronics

It would be helpful if someone posted a bill of materials for the pololu electronics.

The pololu schematic has been hacked, the other half of the pololu boards are missing I think? should be 16 connections not 8 Can some one put the original back?

Any thoughts on reverse voltage detection? When the reprap is Off and the mechanics are moved voltages are induced on the motors and passed back into the system via the 12V connection. It would be nice to at least put a diode 1N4001 or similar in line with the motor supply to prevent this. Or am I missing something?

The 47k pull up on the MS2 and MS3 pins is inappropriate because there is an internal 100k pull-down on those pins. This effectively creates a 1/2 voltage divider, which should lead to unreliable microstepping. RyanTM 18:18, 10 June 2011 (UTC)
