My DIY boards.
These boards have not been tested under every circumstance and may have bugs. Manufacture at your own risk!
Standard pinout for Pro-Micro board
GPS power consumption measurements
Find update-nice_nano_bootloader-0.9.x, and copy the uf2 across to your pro-micro.

- 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

- HT-CT62 based
- Pretty complete
https://github.com/ndoo/ikoka-nano-meshtastic-device
- Uses NRF52 based Xiao board
- Uses a 30db radio module, 1W of power in a very small package

- Uses NRF52 based Xiao board
- Shows the basic pinout and procedures for making the basic node.
- The original!
