ESP-WROOM-32 Breakout Board PCB (55x52mm)
ESP-WROOM-32 Breakout Board PCB – 55x52mm with Full GPIO Access
The ESP-WROOM-32 Breakout Board PCB is a full-featured development platform built around the ESP32-WROOM-32 module. It breaks out all 38 GPIO pins to standard 2.54mm headers, includes a USB-C port with CP2102 USB-to-UART bridge, auto-programming circuit, and dedicated reset/boot buttons. This compact 55x52mm board eliminates breadboard clutter for swift IoT prototyping.

Compatibility
This board is compatible with the Arduino IDE, MicroPython, and ESP-IDF frameworks. It interfaces easily with common sensors and actuators via I2C, SPI, and UART. The 5V input and 3.3V logic levels match most hobbyist components.
Wiring Notes
Connect a 5V supply to the VIN pin or simply use the USB-C port for power and programming. All GPIOs operate at 3.3V—never exceed this voltage. For I2C devices, enable internal pull-ups or add external 10kΩ resistors if the lines are long.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with the Arduino IDE?
Yes, install the ESP32 board package and select “ESP32 Dev Module” as the board. Examples and libraries work out of the box.
Does it include the ESP-WROOM-32 module?
Yes, the module is pre-soldered onto the PCB, so you can start coding immediately without extra hardware.
What is the typical power consumption?
In deep sleep mode, the board draws under 10 µA. During active Wi-Fi transmission, it peaks around 200 mA.
