Other peoples boards:

Fake-tec - NRF52840

https://github.com/gargomoma/fakeTec_pcb/

• Uses the same NRF52840 Pro-micro boards as my designs above
• An excellent design, using the outline of the Heltec v3 to take advantage of all the cases out there.
• Has a voltage divider built-in, with thru-hole or SMD resistors
• Can flush-mount the PCB to reduce height even further

https://gitlab.com/paulhausk/CheapMesh/-/tree/main

• HT-CT62 based
• Multiple options to power & interface
• Initial issue has native USB d+/d- switched - check before building
• Has components on the underside that make it harder to assemble

• RP Pico (or clone) as MCU
• Uses RA-01SH, but can also use HT-RA62
• Changes in code not really required - see TCXO_OPTIONAL
