Product Description
The M5Stack Dial v1.1 - ESP32-S3 Smart Rotary Knob is a wireless MCU module for embedded and IoT applications. Version K130-V11 uses the Stamp-S3A as its main controller, based on the ESP32-S3FN8 with dual-core Xtensa LX7 CPU architecture running at up to 240 MHz and 8 MB of flash memory. The board integrates a 1.28-inch round TFT touchscreen with 240 x 240 pixel resolution, a high-precision rotary encoder, and an RFID detection module.
Additional onboard functions include an RTC circuit, buzzer, and under-screen buttons for user input and wake-up signaling. Power design supports a wide 6 to 36 V DC input range and also provides a 1.25 mm 2-pin lithium battery connector with charging circuitry. Reserved PORT.A and PORT.B interfaces simplify expansion with I2C and GPIO peripherals.
