The ETS IOT WDM board is built around a dual-core ESP32 chip with 4MB of SPI flash onboard, providing both LoRa, LoRaWAN, Wi-Fi and Bluetooth LE via a “3D antenna” on the PCB.
The board’s LoRa support operating at 868MHz with an included SMA antenna.
The board can be programmed using the Arduino development environment, and the example code shows you how to both send and receive data via LoRa.
Flipping the board over there is a battery holder for a 18650 Li-Ion cell, and while a 18650 sort of looks like a “standard” AA battery, it’s significantly different. So don’t make the mistake of substituting in the more common AA battery to try and power the board. They’re not quite the same size, but I’ve seen people attempt this substitution nonetheless.
