Nice boards!!
Because I have my cargo bike shared with my wife, and there is no Garmin display on it, it is hard to use the wireless remote - I really miss a display.
I decided to buy a SW102 because it is small as we like. Then when opening the SW102 to solder the wires and install the bootloader, I destroyed it because the board inside was totally different then the ones I had previously. So, I decided to not spend money anymore on this displays and instead build one based on the wireless controller and a small display, as small as the SW102. Small so it can be made robust with a thick 3d printed case and not be something eye catching for when I park my bicycles on the street for some hours.
And I own a popular cheap electric scooter Xiaomi M365, with OpenSource firmware and with many improvements / mods to be done. I need a custom display for it so I will reuse this one (it needs connection to throttle and brake signal, as this ones are sent by UART to the motor controller).
My idea is to reuse the SW102 firmware that we did develop and add the Bluetooth and ANT+ from TSDZ2 wireless, including the same mobile app. From the hardware perspective, is like the TSDZ2 wireless wired remote + display.
To the TSDZ2 wireless board, we just need to add 4 wires (Vcc 3.3V) to connect to this 0.96 inches OLED display:
And here is our the display firmware for SW102, I do not expect more then this. I wish to see on the display the battery SOC, when the motor is on/off, wheel speed and the current motor power (in percentage, relative to max configured value):
