This is a lite version of Wireless Stick with a ESP32-PICO (dual-core 32-bit MCU + ULP core + Internal 4MB FLASH) processor, LoRa node chip SX1276 (alternate to SX1278 or SX1262) and Micro USB interface with 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;
