ESP32 is Espressif’s successor to the popular Wifi-module ESP8266 and is now a fully fledged IoT microcontroller. The ESP32-WROOM32 is a surface mount module intended for integration in home-brewed projects, and has functions for almost any application. Among these are bluetooth and Wifi for wireless communication, SDIO, UART, SPI, I2C, I2S, LED PWM, Motor PWM, IR, capacitive touch sensors, ADC, DAC, LNA preamps, a hall effect sensor, temperature sensor… A highly capable platform. For documentation, user guides, a forum and more, have a look at the the manufacturer’s website to the right.
The ESP32-WROOM-32 requires external components to function. For a complete solution ready to use, see article no. 41015393.
