This firmware is intended to replace the original Bafang firmware on the BBSHD/BBS02 motor controller. Almost all functionality of original firmware has been implemented and additional features have been added.
This firmware is compatible with all displays that works with the original Bafang firmware. A custom configuration tool is provided since BafangConfigTool is not compatible due to a different set of supported parameters.
The firmware is also compatible with the TongSheng TSDZ2 controller but requires a custom made cable in order to interface with Bafang compatible displays.
⚠️ Warning: The firmware should NOT be flashed or configured while the eBike battery is charging!

There are compatibility issues reported, this firmware is suspected to be incompatible with older BBS02 controllers. If you have a newer BBS02B you are probably fine, if you have an older controller it might not be a good idea to flash this firmware.

BBS02A - No idea, not tested, not recommended to try unless you have an already bricked controller.
Compatible with TSDZ2A/B using the STM microcontroller (which is nearly all off them).
Only displays with the Bafang display protocol can work.
Also the controllers need to be those, that are officially designed by Bafang, respectively Tongshen.
Some shops sell kits with their own controller.
