Can't find EBYTE test board E73-TBM-01 V1.0 schematic, so figured out connections by myself:

NRF52832	E73-2G4M04S1B	Connected to
P0.05	21	CH340G CTS
P0.06	22	CH340G RX
P0.07	23	CH340G RTS
P0.08	24	CH340G TX
P0.13	29	SW2 (act. low)
P0.14	30	SW1 (act. low)
P0.17	33	LED1 (act. low)
P0.18	34	LED2 (act. low)

I found the schematics in the EBYTE website, here is the link:

They call the board TBX, I assume it is because the last char means only some PCB design version

Thanks load guys ! helps a lot !
