This document branch is for Heltec STM32 + LoRa Node series.

STM32 is a powerfull SoC with Ultra-low-power 32-bit MCU,The benefit of “STM32 + LoRa” combination:

  • Low power features;

  • Multiple bus interfaces;

  • Powerful computing skills;

  • Power mananagement system and different types of batteries support;

  • Multiple general GPIOS;

  • LoRaWAN 1.0.2 protocol support.


This series boards also don’t have an onboard USB-UART bridge. If plug it directly into a computer, it may prompt “Unrecognized USB device”, which is normal.
