Features
When we use a MCU to drive an 8*8 dot matrix, we need to use a total of 16 digital ports, which greatly wastes the MCU data.therefore, we specially designed this module which uses the HT16K33 chip to drive an 8*8 dot matrix, we only need to use the I2C communication port of the MCU to control the dot matrix, which greatly saves the MCU resources.
The sensor is compatible with various MCU control boards, such as the for Arduino series of MCU. When using it, we provide a method to use this sensor with the Arduino series of microcontrollers.
The module comes with 3 DIP switches, which allow you to toggle the switch freely.
