Overview

Product Overview

The classic ESP32 dev board, done properly: an ESP-WROOM-32 module (ESP32-D0WD-V3, dual-core up to 240 MHz, 520 KB SRAM, 4 MB flash) with Wi-Fi 802.11 b/g/n plus Bluetooth Classic and BLE, a CP2102 USB-to-UART bridge on a USB-C port, and 38 pre-soldered pins. You get about 25 usable GPIO, 18 ADC channels, 2 DACs, 10 touch pins and I2C, SPI, UART, I2S, CAN and SDIO buses. Logic is 3.3 V and not 5 V tolerant.

Program it from the Arduino IDE (esp32 core), ESP-IDF, MicroPython or PlatformIO, or flash ESPHome or Tasmota for Home Assistant. Power it over USB-C or 5 V on VIN. It is the board behind most of our ESP32 tutorials — sensor nodes, MQTT devices, relays, displays and robots. Single or 2-pack.

Questions & answers

Frequently asked questions

Yes. It is an ESP32 development board with a CP2102 USB-to-UART interface, so it can be programmed from Arduino IDE when the ESP32 board support is installed, and it is also suitable for ESP-IDF workflows.
Yes. The headers are preinstalled, so the board is ready for breadboards, jumper wires, and quick peripheral connections without soldering. This helps with fast prototyping, classroom labs, and testing sensor or module hookups.
It uses a USB-C connector with a CP2102 USB-to-UART chip for programming, serial monitoring, and power. The ESP32 GPIO are 3.3 V logic, so use appropriate level shifting when connecting 5 V devices.
It is well suited for WiFi and Bluetooth connected prototypes such as smart home controllers, MQTT devices, sensor nodes, robotics experiments, and automation projects. The 4MB flash supports typical firmware and iterative development builds.
Use a data-capable USB-C cable, not a charge-only cable. If the serial port still does not appear, install the CP2102 driver, select the correct port in your development tool, and verify the board is powered.
