Known Firmware Versions

Posted: May 15, 2020, Updated: October 15, 2023

This is a list of firmware updates that I’ve seen or found sources for. Have a Screenshot/Reddit Post/Tweet that shows more? Open a GitHub issue, and I’ll update the table.

ESCs and batteries can have firmware updated independently. You can use Dustin’s BLE Board Info page in the Tools menu to see what firmware you have on your board and battery from your web browser.
