5. KEYESTUDIO ESP32 MAIN BOARD

5.1 5.1 Introduction

Based on ESP-WROOM-32, the keyestudio ESP32 Core board is a mini development board, whose I/O pins are reserved
a space of 2.54mm on both sides, so that it can be connected to peripherals according to needs. In addition, these pins
also make your operation more concise and convenient when using and debugging.
The ESP-WROOM-32 module adopts industry's leading WiFi + Bluetooth solution. Its external components is fewer
than 10, including an antenna switch, RF balun, power amplifier, low noise amplifier, filter and power management
module. It also integrates TSMC low-power 40nm technology, featuring high power performance and RF performance.
Besides, it is safe, reliable, and easy to expand to various applications.
