ADIY ESP32 Development Board Compatible with UNO

Description

The ADIY D1 R32 is a powerful development board based on the ESP32-WROVER-32 module, designed to combine advanced wireless capabilities with the familiar Arduino Uno form factor. It supports both Wi-Fi (802.11 b/g/n/e/i) and Bluetooth 4.2 (Classic + BLE), making it ideal for IoT, robotics, automation, and wireless communication projects.

The board features a USB Type-C connector for programming and debugging, a CH340C USB-to-UART bridge, and an onboard 3.3V regulator for safe power delivery. With 38 multifunctional GPIO pins, it provides rich peripheral support including ADC/DAC channels, PWM outputs, I²C, SPI, UART, and capacitive touch sensors.

Designed for flexibility, the D1 R32 allows users to swap the default ESP32-WROVER module with an ESP32-WROOM module, enabling hardware customization depending on memory and performance needs. This makes it a versatile platform that bridges the simplicity of Arduino with the power of ESP32, suitable for students, makers, and professionals alike.
