Meshtastic Heltec CT62 tiny board

DIY PBC for Meshtactic messenger, based on Heltec CT62 Lora module.

Tiny (near 3x4cm), only few smd for minimal setup.

Allows add I2c display/sensors and LiPo charging circuit.

Unfortunally, MCU (esp32c3) is not very energy effective, so battery life not too long (heltec board consumes near 0.5w)

FW variant is working minimum, need to check it for completeness.

Used custom fw variant, but possible official variant for ct62 can be used, need to check.

Many thanks Meshtastic team for great project!
