    Description

    This ESP32 development board ships with the ESP32-WROOM-32U module installed. This module contains the latest revision of the ESP32 IC and is compatible with the ESP32-WROOM-32 Rev1 module. Pin numbers on the top of the PCB and low cost for a breadboard friendly development module.  Sleep mode current is 17uA.

    Made in and ships from the USA.


    Other than the ESP32-Wroom-32U module it has an Si Labs CP2104 USB to Serial converter, A 500mA 3.3V LDO, Reset and Flash Switches and a multi color LED.

    There are two tri-color LEDs on the board.  One has the red and green LEDs hooked up to the CP2104 to signal transmit and receive activity and the other is connected to three IO pins on the ESP32S module.

    The board supports auto-download from the Arduino environment and will automatically be set in download mode by the downloader.  Once the download is complete the board will be reset, just like a normal Arduino board.

    All the required capacitors and pull-up resistors are fitted on the board.  The board can be powered from an external power supply of up to 12V or the USB connector or both.

    Unlike most other boards this one fits on a breadboard and has one row of pins accessible on each side of the board. Most of the pins of the ESP32 module are available on the external pins.  The board ships with header pins but they are not soldered to the board.  The breadboard is not part of the listing.

    The module can be programmed directly from the Arduino environment without pushing any buttons.  The upload speed is 921600 bps.


    The module contain an IPEX connector for an external antenna.
