To build this interface You will need some cheap element:
One USB-C to TTL interface : https://pl.aliexpress.com/item/1005008104567290.html?spm=a2g0o.order_list.order_list_main.28.7daa1c24NlzL2N&gatewayAdapt=glo2pol
Three 5,5 mm long pogo pins: https://pl.aliexpress.com/item/1005005982247106.html?spm=a2g0o.order_list.order_list_main.34.7daa1c24NlzL2N&gatewayAdapt=glo2pol
One M3 x 10 screw
After soldering the wires to the pogo pins, ensure there is no short circuit between them; then, solder the wires to the TTL interface board according to the diagram:
GND -> GND,
RT -> TX,
TX -> RX.
Before assembling the housing, verify that the interface is working correctly, as the fit is very tight and opening the case can be somewhat difficult.
