Hi I started making the display for https://opensourceebike.github.io/
However I gave up as I have zero time - I think the nRF52840 may be dead.
Anyway everything else I think is fine.
Includes
SPI OLED (no flicker that you get with i2c)
possibly dead nRF52840 possibly not
XP Power STH0548S05
BTS4140N
BSP296
3 button remote
TSDZ2 cable
3D printed enclosure
You just need an stlink v2 and possibly replace the nRF52840
