ESP32 Dev Board WiFi+Bluetooth with CP2104 USB to Serial. Arduino Programmable.  Designed and Made in the USA

Here is my ESP32 development board. Made in and ships from the USA. Other than the ESP32 module it has an Si Labs CP2104USB to Serial converter, A 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 FT231 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 module can be programmed directly from the Arduino environment without pushing any buttons. The upload speed is 921600 bps.

The module has been designed to be used in Sleep mode without excessive current draw.  I read 17uA when powering from the Vin and Gnd pins.with the processor in deep sleep mode.  By removing Schottky Diode another few uA can be saved but then the board must be powered by the Vin pin while programs are downloaded.

The schematic is available under the Downloads' tab above.

  1. Great product by this company Review by BBQ_Bailey

    I have bought 10 of these devices from this company, and plan on buying more. Their prices are very competitive and arrived in the time specified. All units have work as advertised. I particularly like the built in RGB LEDs for my projects. I especially like that they are built in the USA. Atlanta GA USA (Posted on 3/9/18)

  2. Nice board Review by A

    Good board, I must have an early edition (no pin labels)
    Works well with Arduino IDE.
    Loads programs without issue.
    Haven't tried the Wi-Fi yet, but it works like an Arduino.
    Recommend addressing pins by number to avoid compiler errors.
    Have yet to try addressing by direct port manipulation.
    Tri-color LED on Pins 16, 17, 18 is nice touch, way more fun than standard blink.
    Great board, at a great price, and they ship quick too. Get a couple before they're all gone.

  3. Awesome board Review by Jason

    I love that it has RGB LEDs for testing. The board layout is great and I haven't had any issues on multiple boards. The ESP-WROOM module can get kinda warm, but I glued a heatsink on the metal case for long-term reliability until I can get some sleep time on my programs. (Posted on 6/12/17)
