Keyes Brick 8*8 Dot Matrix Module with Pin Header I2C Communication

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 Specifications Working voltage DC 5VPositioning hole size 3mm in diameterCommunication method I2C communicationI2C communication address 3 dial switch settingsDot screen display color redSize 50 x 31 x 9mmPackage included 1 x Module Board
