It comes equipped with a 1.28\" round TFT touchscreen, a rotary encoder, RFID detection, an RTC circuit, a buzzer, and under-screen buttons, making it user-friendly for creative projects.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eDriving the show is the M5StampS3 controller, based on the ESP32-S3 chip, offering essential features like Wi-Fi and various peripheral interfaces like SPI, I2C, UART, and ADC. It's got a decent 8MB of built-in flash storage, so you won't run out of room for your projects.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eThe rotary encoder isn't just for show – it's there to make adjusting settings easy. It allows you to tweak the volume, and brightness, or manage your home devices, and the built-in display screen keeps things simple and interactive. Compact and lightweight, the M5Dial suits various embedded applications, from smart home controls to industrial automation systems. \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe RFID detection feature recognises RFID cards and tags at 13.56MHz, which is useful for access control and identity verification. Additionally, it includes an RTC circuit, buzzer, and a physical button for sound prompts and wake-up operations. Powering up is hassle-free. It accepts 6-36V DC input and even plays nice with external Lithium batteries.
