Right now it is very hard or impossible to find scheme for connecting nrf52 to TSDZ2. A lot of links are 404.

Sorry, I need to work on that. What are you looking for? To the display or to the TSDZ2 wireless??

I kind of achieved the documentation for the TSDZ2 wireless, see it here: https://github.com/OpenSourceEBike/OpenSourceEBike.github.io/blob/main/tsdz2_wireless/index.md

I wrote at bottom of the main page a link to TSDZ2 wireless documentation.

Can you please explain what you like on TSDZ2 wireless? how you will use it? will you build the fully wireless remote or use the wired remote?

I'm interested in building Wireless TSDZ2. All those displays are too bulky (except sw102) so it makes sense to just use my phone or optionally a remote.

I managed to flash and solder Wireless TSDZ2, however, I probably burnt my nrf52. Used converter is a DD8024TA. Voltage IN 51V, OUT 5V connected to vbus. And nrf52 immediately heats :(

So I ended up buying a new SW102, I'll upload @anszom's firmware. Would be cool to make SW102 to work with an app.

I can't imagine why NRF52 board did burn, all seems ok - well, only that it should not be placed on top of conductive pads as you seem did it.

Ok, the OpenSource display is simultaneously the TSDZ2 wireless + the SW102.

@casainho I did insulate nrf52 with a tape.

Ok, good. So, if you flashed the bootloader with the STLinkV2 and power up the biard with it, that should not happen with the DD8024TA dc-dc. I now recomend to the display to first flash the bootloader with STLinkV2 powe up the board, then solder only the DC-DC and test with a multimeter the 5V output and only after connect to the NRF52 board.
