Multi-Function ESP32 IoT Experiment Board with SHT30, QMP6988, Relays, Motor Control, RFID, and Industrial Interfaces
The M5Stack K024-B Demo Board-SHT30 is a comprehensive IoT learning and hardware-development platform designed for use with compatible M5Stack Core controllers. It combines environmental sensing, analogue and digital signal processing, motor control, relay switching, user-input interfaces, RFID, lighting, and industrial serial communication on a single experiment board. The onboard environmental section includes an SHT30 temperature/humidity sensor, QMP6988 barometric-pressure sensor, light sensor, and microphone for practical sensor-acquisition experiments.
The board further integrates 4-channel ADC and DAC interfaces, 8-channel relay control, an 8 × 8 RGB LED matrix, joystick, rotary encoder, 4 × 4 button matrix, MFRC522 RFID reader, servo output, feedback DC motor, four-phase five-wire stepper motor, RS485, and RS232 communication. Independent power switches are provided for individual functional sections, while M5-BUS and prototyping areas support additional hardware expansion. The kit is suitable for IoT education, industrial-interface demonstrations, embedded programming, automation experiments, and multi-function hardware testing.
