WiFi LoRa 32 is a classic IoT dev-board designed & produced by Heltec Automation(TM), it’s a highly integrated product based on ESP32 + SX127x, it has Wi-Fi, BLE, LoRa functions, also Li-Po battery management system, 0.96″ OLED are also included. It’s the best choice for smart cities, smart farms, smart homes, and IoT makers.
NOTE: Some of the photos show V1, but we sell version 2 of this board (V2). Both V1 and V2 are the same size, and look nearly identical.
The development board features a USB-UART Bridge circuit which allows developers to connect the board to a computer’s USB port for flashing, debugging and power.
This board has two rows of standard 0.1”(2.54mm) header pads on both sides for easy access, allowing it to be mounted on a breadboard or prototype board with a standard 0.1" grid.
It can be powered via USB or via the battery connector. The battery connector is a standard 1.25mm SH1.25 2 pin type connector. VERY IMPORTANT! Ensure the polarity of the battery is correct before connecting it!
