                  Introduction:
                  It consists of a keyes ESP32-IO expansion board and a keyes ESP32 Core board
                  Development board composition, when using, only need to input DC 7-12V voltage on the black DC head, then
                  It can supply power to the keyes ESP32 Core board. And the expansion board also comes with 1 dial code
                  Switch, used to control the power switch. Developers can connect peripherals according to their needs. Make
                  When using the development board for development and debugging, the standard headers on both sides can make your operation easier
                  Clean and convenient.
                  ESP-WROOM-32 module is the industry’s leading integrated WiH + Bluetooth solution,
                  Less than 10 external components, it integrates antenna switch, radio frequency balun, power amplifier
                  Converters, low-noise amplifiers, filters and power management modules. At the same time, it also integrates
                  TSMC low-power 40nm technology, power performance and radio frequency performance, safe and reliable, easy to expand
                  Expand to various applications.
