firmware download

Dear Developer,

Could you please help me to get below information:

1. Where to download the source code of the firmware?

2. Do you have a circuit diagram or schematic for the evse and display modules?

3. Can I have the pcb layout cad files?

Thank you!


I just want to point out that the "Firmware" link from ultimately leads to, which is apparently doesn't have the latest production code.
Can you provide a pinout for the 10 pin to 6 pin cable?

 I'm not that familiar with Github, and can't find the change logs for the firmware. My EVSE is 2.5 years old, and I want to see if the new software is worth the hassle.

How safe is the upgrade process? Bricking the EVSE would be problematic.

Thats what I was looking for, also how do I hookup and with what to the wifi module to update, my usb adapter wont connect to it tha I can see, I have the one to update the openevse.

If you just need the files to load and not the source code you can download just a specific binary release. Here is the latest release for each.

OpenEVSE Firmware

Wifi Firmware

Do I need to download all items in the directory od just in the firmware directory. I haven't done this in so long I forget what I need, my opevse is still on 3.10. also what do I need to do to hookup to the wifi module to update it. I think it is still on v 1.x

Dear Christopher,

Well noted with thanks!

Have a nice day!
