Features:

Provide CE certificate;
The main control chip uses ESP32-based ESP32-PICO-D4 module (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276/SX1278;
Integrate WiFi, LoRa, and Bluetooth network connections, and reserve two IPEX (U.FL) interfaces for LoRa and 2.4GHz RF signals.
Support the development environment;
(Exclusive) Supports the 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 produced by the company) The development board is available, the serial number can be queried on this page);
The module has good RF circuit design and low power consumption design (sleep current 30uA), which is convenient for IoT application vendors to quickly verify solutions and deploy applications;
Pin: 1.27mm pitch stamp hole
