Description

A development board designed for IoT projects, equipped with a WiFi/Bluetooth ESP32 module with a 3D antenna and a LoRa communication module operating at 433 MHz. In addition, the board has GPS NEO-6M with a positioning accuracy of up to 3 m. On the bottom of the board there is a basket for a Li-Ion type 18650 battery, which is managed by a circuit with the TP5400 system, which allows you to charge the batteries with a current of up to 1 A. This selection of components and small dimensions make the board ideally suited to the design of devices in the area of the Internet of Things.
