Demo Board-SHT30

SKU: K024-B

Description

Demo Board is a learning and development board. It uses 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, servo), RGB LED light board, integrated multiple sets of relay control and ADC, DAC conversion circuits, supports RS485, 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". The Demo Board will be a great tool for learning hardware and programming.

Note
DAC and ADC functions cannot be used simultaneously because the broadcast addresses (0x48) of the ADS1115 and DAC6574 chips are the same, causing a functional conflict.
