NG3PCB

This board was design to replace the control processor or on a Zivan NG3 charger.  It remaps pins from a Aduino Nano to the old processor pinout allowing the charger to be controlled from the Arduino Nano.  This board has been very lightly tested in one NG3, and there is no assurance of any kind that it will work for you or your controller.  By using this you affirm that you have sufficient skills to understand the problems and risks of such a project, including realizing that the contoller exposes high voltages that could potentially be lethal.

There's a version that saves memory by using a text display on the "TextDisplay" branch here: https://github.com/ergouser/Zivan-NG3/tree/TextDisplay/Zivan%20NG3%20Project

A history of the project is here (this project appears about page 7 or 8) and this is the best place to ask for help:
