Wireless ESP32 Module SX1276 LoRaWAN Protocol WiFi BLE Heltec for Arduino - products that work with official Arduino boards

Get Wireless ESP32 Module SX1276 LoRaWAN Protocol WiFi BLE Heltec for Arduino - products that work with official Arduino boards

Feature:

 

-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;
