Build connected projects with ESP32

Turn a sensor reading into a wireless dashboard, prototype a smart-home controller, or add Bluetooth connectivity to your next robotics build. This ESP32 WROOM-32 development board combines a dual-core processor, WiFi and Bluetooth with a 38-pin layout, USB Type-C connector and CP2102 USB-to-UART interface for programming and serial communication.

Key features

Built-in wireless connectivity: 2.4 GHz WiFi 802.11 b/g/n and Bluetooth v4.2, including Bluetooth Classic and BLE.
Dual-core processing: Adjustable processor clock from 80 MHz to 240 MHz for embedded control and connected applications.
USB Type-C connection: Connect the board to your computer for programming, serial monitoring and USB power.
CP2102 USB-to-UART bridge: Provides the serial interface between your computer and the ESP32.
38-pin development layout: Access power, ground and signal pins for connecting compatible sensors, displays and peripheral modules.
Flexible programming: Develop with Arduino IDE, MicroPython or ESP-IDF.

Before you start

Use a data-capable USB Type-C cable for programming. Your computer may require a CP2102 driver, and your development environment must be configured for ESP32. Check the board pinout before connecting peripherals: the 38-pin count includes power and ground connections and does not mean 38 usable GPIOs. Confirm peripheral voltage compatibility with the board’s 3.3 V logic.

Low-power modes are available on the ESP32, but total development-board power consumption depends on the regulator, USB interface, connected peripherals and firmware. Chip deep-sleep figures should not be treated as whole-board consumption.
