Description
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, with the NODEMCU-32S pinout. It measures 55mm x 29mm x 14mm.
