Description
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)
Github link for project: https://github.com/mrekin/MeshtasticCustomBoards/tree/main/firmware/variants/diy/diy-heltec-ct62-tiny-1.02
Used custom fw variant, but possible official variant for ct62 can be used, need to check.
Many thanks Meshtastic team for great project!
