This is a development board for the ESP-WROOM-32 module from Expressif Systems. A further development from the popular ESP8266 modules, this comes with both Wifi and Bluetooth. It is supported by the Arduino IDE, and also supports Micropython and there is developing support for NodeMCU Lua.
There are different variations of these development boards available. They offer similar capabilities but with different pinout configuration. This listing is for the 38 (2 x 19) pin layout, sometimes called the DevKitC Development board. It measures 55mm x 29mm x 14mm.
The board has a Micro USB port onboard, soldered headers and integral antenna. It's well documented online, and is a very capable board, with plenty of digital and analog input/outputs.
Orders received before 10am on normal weekdays will be posted the same day (we will try our best with later orders too!). Orders received later, or on public holidays/weekends will be posted the next business day. We will post Royal Mail 2nd Class at no charge. If you want faster delivery, please ensure you select Royal Mail 1st Class - or if you are really in a hurry there is an option for guaranteed delivery by 1pm the next business day.
Technical details:-
The USB interface uses a Silicon labs CP210x chip. Drivers are required for most operating systems, but are freely available :
Ebay does not allow us to include links to documentation or drivers on our listings. Device drivers for this board can be found by performing an internet search for “CP210x USB to UART Bridge VCP Drivers"
Extensive documentation is available on the Expressif website.

These are wide boards with 25mm spacing between the pin headers. Some breadboards (including MB102 boards) will have all the holes covered on one side, and it may be necessary to use two breadboards to have full access to the pins.
