Keyes Aurduino EASY PLUG starter kit

The EASY PLU GKeyestudio Starter Kit is a development board based on the ESP8266-12F WIFI module developed by Ai-Thinker. The ESP8266 processor integrates the industry-leading 32-bit Tensilica L106 ultra-low power micro MCU in a smaller package and 16-bit Lite mode. The main frequencies supported are 80 MHz and 160 MHz. Supports RTOS, integrated with Wi-Fi MAC/BB/RF/PA/LNA. The integrated comes with a curved antenna. The development board is a standalone network controller that can add networking functionality to these existing devices. When using, power the board and load the program via the Micro USB port and the current should be 2 A.
