This development board combines the same architecture as an Arduino Uno and the popular ESP32 Wifi module (meaning the pin-outs are based on the ESP32 form and not the UNO's) to bring you a small and compact board, that will make your next IOT project much easier.
Development board based on the ESP32 takes the original format of the Arduino Uno rev.3. Programming can be done directly from the Arduino or PlatformIO IDE using the micro-USB port. The card can be powered from the micro-USB port or by an external 5-12V DC power supply.
Input Voltage 7-12V (recommended)
IO Pins are 3.3V and not 5V
Arduino UNO Architecture
Soft Serial or Hardware Serial Connection
Integrated ESP-Wroom-32 Wifi Module
