Keyestudio ESP32 Core Board(38 Pin)

This keyestudio ESP32 core board is a Mini development board based on the ESP-WROOM-32 module.

The board has brought out most I/O ports to pin headers of 2.54mm pitch. These provide an easy way of connecting peripherals according to your own needs.

When it comes to developing and debugging with the development board, the both side standard pin headers can make your operation more simple and handy.

The ESP-WROOM-32 module is the industry's leading integrated WiFi + Bluetooth solution with less than 10 external components.
It integrates antenna switch, RF balun, power amplifiers, low noise amplifiers, filters and power management modules.
At the same time, it also integrates with TSMC's low-power 40nm technology, so that power performance and RF performance are safe and reliable, easy to expand to a variety of applications.
