Overview

Product Overview

ESP32 UNO D1 R32 development board is a WiFi and Bluetooth microcontroller board built for connected electronics, IoT devices, and rapid prototyping. Based on the ESP32 with 4MB flash, it gives you wireless networking plus ample program storage for sensors, automation, data logging, and robotics projects. The onboard CH340G USB-to-serial interface and Type-B USB port provide straightforward programming and serial communication from a PC, while the UNO-style layout makes it a practical option for makers working with Arduino IDE, ESP32 libraries, and common development workflows.

Questions & answers

Frequently asked questions

Yes. It is intended for common Arduino IDE ESP32 workflows using ESP32 board support and libraries. The UNO-style layout is convenient for Arduino users, but it is not the same microcontroller as an Arduino Uno.
No soldering is needed just to program or use the board over USB. Connect a Type-B USB cable to a computer; install the CH340G driver and ESP32 board support if your system requires them.
ESP32 GPIO uses 3.3V logic, so connected sensors or shields should be compatible with 3.3V signals. Do not feed 5V logic directly into ESP32 GPIO unless proper level shifting is used.
It fits connected electronics such as sensor nodes, home automation, WiFi data logging, Bluetooth control, and small robotics prototypes. The ESP32 provides wireless networking, while 4MB flash supports typical embedded application firmware.
Use a data-capable Type-B USB cable, not a charge-only cable, and confirm the CH340G driver is installed if the serial port does not appear. Also check the selected board and port in your IDE.
