ESP32 Series


This document branch is for Heltec ESP32 Node series.

ESP32 is a powerfull SoC with 240MHz Tensilica LX6 dual-core & 1 ULP core, 600 DMIPS, 520KB SRAM. The benefit of “ESP32 + LoRa” combination:

  • Multi wireless communication technical on board, include Wi-Fi, BlueTooh/BLE, LoRa;

  • Powerful computing skills;

  • Large FLASH size;

  • Power mananagement system and Li-Po support;

  • Arduino-compitable;

  • We also provide LoRaWAN-Node protocol Arduino library;


ESP32’s BlueTooth and Wi-Fi antenna use a same pin, so BlueTooth and Wi-Fi can’t work at the same time.
