Freematics ESPRIT -- ESP32 in Arduino UNO form factor


Freematics ESPRIT is an Arduino compatible development board based on Espressif ESP32 SoC designed for casual or serious IoT and telematics projects. The board leads out nearly all I/O pins from ESP32 into standard Arduino factor, making it familiar to Arduino players and also compatible with some existing Arduino shields.
