alfu Posted May 28, 2017 Share Posted May 28, 2017 Here is an image of the controller board from my generic electrically locked up Step-n-Roll, with wire color codes, for reference. If anyone has information on the undocumented connector lands, I will be happy to update the image and re-post. Link to comment Share on other sites More sharing options...
electric_vehicle_lover Posted May 28, 2017 Share Posted May 28, 2017 I did a simplified schematic for generation 1 boards on KiCAD:https://github.com/EGG-electric-unicycle/electronics-gen1_boards/tree/master/generic_electric_unicycle Please post the ICs reference name. That boards seems more like MicroWorks 30B4 board (gen 2). Link to comment Share on other sites More sharing options...

It looks like I may be having to do a reverse-engineer of this board as well. The short-to-GND calibration jumper looks like it also is a comm port to set various attributes of the board. To get mine working again I will have to find out what the reset-to-factory-defaults protocol is to get it out of its locked-up state. I'm trying the vendor first (http://kidsatvparts.com/clearance.html 713 588-1681), after that, not sure where to turn. Link to comment Share on other sites More sharing options...
