Wi-Fi, BLE and LoRa, LoRaWAN module

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;
