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

Here is my brand new ESP32 development board. Made in and ships from the USA. Other than the ESP32 module it has an FTDI FT231XS USB 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 schematic is available under the Downloads' tab above.
