Bit-Tree Creativity - 8×8 Dot Matrix Module 20×20

8×8 Dot Matrix Module 20×20 (A065)

This 8×8 dot matrix module adopts LED1088AS serial-in parallel-out driver. It works with wide 3.3V–5V voltage supply and uses 3-wire control (CLK/CS/DIN). Optional colors: red, green, blue and white. It features high brightness, simple wiring and cascading support. Suitable for expression animations, scrolling numbers, pattern display, maker education and other applications

It adopts three-wire serial communication, occupying only DIN, CLK and CS ports to effectively save MCU IO resources. Equipped with power indicator, pin header and XH2.54 dual interfaces for easy wiri

Built-in 64 LED beads. Static/dynamic scanning drive ensures even illumination and low power consumption to prevent screen burn. Red, green, blue and white monochrome versions are available to satisfy

The driver chip supports serial cascading. Multiple modules can be connected in series to realize large-area spliced display. Mounting holes are reserved on four PCB corners for easy installation on e
