Introduction

1.The ESP32 Arduino development board (ESP32 UNO D1 R32) is an opensource development board based on the Espressif ESP-WROOM-32 module.Its Arduino UNO-compatible form factor gives direct access to the rich Arduino shield ecosystem, and it fully supports secondary development.

2.The board breaks out every pin of the ESP32 module and integrates Wi-Fi,Bluetooth 4.2 (BR/EDR/BLE) and an Ethernet MAC, with 4MB Flash and a dualcore processor. Together with the onboard CH340C USB-to-serial chip, a single USB cable handles both power and firmware download — an ideal platform for IoT, smart hardware and embedded development.
