“Wireless Shell” is an ESP32-PICO + SX1276 module. provide Wi-Fi, BLE and LoRa solution. You can regard it is the module version “Wireless Stick Lite” with better low power feature(10uA in deep sleep). 38.4 x 16.1 x 3.2(mm) size with 1.27mm stamp holes package makes it’s can be assembled into your PCB or products directly.

``Wireless Shell`` is a module, must work with other PCB boards, it belongs to “Heltec LoRa“ series, with the following features:

  • CE Certificate;
  • Main control chip ESP32-PICO (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276;
  • RF shielding(contain a shield shell) and other protection measures;
  • Integrated WiFi, LoRa, Bluetooth network connections, both of them are IPEX socket;
  • Support the Arduino development environment;
  • (Exclusive) Supports the Arduino version of the ESP32 + LoRaWAN protocol routine provided by Heltec. This is a standard LoRaWAN protocol that can communicate with any gateway/base station running the LoRaWAN protocol (requires serial number activation, only the development of the company) The board is available, the serial number can be queried on this page);
  • With good RF circuit design and basic low-power design (sleep current: 10uA theoretically), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
