Demo Board
Description
Demo Board is a learning and development board. It uses the M5Core as the control core and is fully compatible with the module stacking and hardware expansion system. It is equipped with multiple sets of environment detection-related sensors and provides various input methods such as joystick, rotary encoder, matrix buttons, and wireless radio frequency identification. It includes three motor driving methods (DC, stepper, and servo), an RGB LED panel, integrated multiple sets of relay control, and ADC and DAC conversion circuits. It supports RS485 and RS232 bus communication and provides an independent power switch for each module. Combined with the IoT-enabled M5Core as the control core, the onboard modules cover multiple aspects of "sound, light, electricity, and force," making the Demo Board a powerful tool for learning hardware and programming.

Note: The DAC and ADC functions cannot be used simultaneously because the ADS1115 and DAC6574 chips share the same broadcast address (0x48), causing a functional conflict.
