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

The board brought out most of the I / O ports on pin headers with a pitch of 2.54mm. These offer a simple way of connecting peripheral devices according to your own needs.

When it comes to developing and debugging with the development board, the standard double-sided headers can make your job easier and more convenient.

The ESP-WROOM-32 module is the industry-leading integrated WiFi + Bluetooth solution with less than 10 external components.

It integrates antenna switches, RF balun, power amplifiers, low noise amplifiers, filters, and power management modules.

At the same time, it is also integrated with TSMC's low-power 40nm technology, so the power and RF performance is safe and reliable and can be easily expanded to a wide variety of applications.
