3PCS Keyes ESP32 Core Board Development Expansion Board Equipped with WROOM-32 Module

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 industryas 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.
