M5Stack K130 - Smart knob with circular touch screen

Description

M5Stack K130 is a versatile development board for smart home applications. It features a 1.28-inch round TFT touch screen, rotary encoder, RFID module, RTC, buzzer, and under-screen buttons, enabling the implementation of creative projects. The main controller is the M5StampS3 with an ESP32-S3 chip, offering high performance and low power consumption, with Wi-Fi support and various interfaces. The standout feature, the rotary encoder, allows precise control of functions like volume and brightness. Its compact size and lightweight design make M5Stack K130 ideal for embedded applications. The RFID module operates at 13.56 MHz, supporting functions like access control. RTC maintains accurate time and date, while the buzzer and buttons provide sound notifications. The board supports 6-36V DC power input and has a battery port with a charging circuit. Two reserved interfaces, PORTA and PORTB, support I2C and GPIO extensions. M5Stack K130 is compatible with Arduino, UIFlow, and ESP-IDF, enabling easy programming.
