ESP32 Boards

The ESP32 is one of the most powerful and complete microcontrollers commonly used in DIY projects by makers.

It has everything that a classic microcontroller has: GPIO, PWM, Timer, ADC, DAC, I2C, SPI, PWM, SD with in addition WiFi and Bluetooth and a low power consumption mode. It is therefore much more judicious to buy a single ESP32 board which contains all these functionalities instead of buying an Arduino board then a Bluetooth module and a Wifi module.

Here are the uPesy boards based on an ESP32:
