WiFi LoRa 32 is a part of the “Heltec LoRa“ series, with the following features:

  • CE Certificate;
  • Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276/SX1278;
  • Micro USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures;
  • Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching);
  • Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal 3D antenna, reserved IPEX (U.FL) interface for LoRa use;
  • Onboard 0.96-inch 128*64 dot matrix OLED display, which can be used to display debugging information, battery power, and other information;
  • Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
  • Support the Arduino development environment;
  • We provide ESP32 + LoRaWAN protocol Arduino® library, this is a standard LoRaWAN protocol that can communicate with any LoRa gateway running the LoRaWAN protocol. In order to make this code running, a unique license is needed. it can be found on this page;
  • With good RF circuit design and basic low-power design (sleep current ≤800uA), it is convenient for IoT application vendors to quickly verify solutions and deploy applications.
