Many users need a version without OLED display, because they want to use it directly in their IoT projects as the main controller and RF (LoRa, Wi-Fi, BLE) connection. Compare with Wireless Stick, “Wireless Stick Lite” has much better low power design (30uA in deep sleep). Removed the 0.49″ OLED, use ESP32-PICO MCU (it’s more friendly for low power design),

Wireless Stick Lite is a part of the “Heltec LoRa“ series, with the following features:

  • CE Certificate;
  • Microprocessor: ESP32-PICO (dual-core 32-bit MCU + ULP core + Internal 4MB FLASH), with LoRa node chip SX1276;
  • 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;
  • Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
  • 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 good low-power design (sleep current ≤ 30uA), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
