This document branch is for Heltec ESP32 + LoRa 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;

Tip

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