5Pcs MAX7219 Dot Matrix Display 4-in-1 Display Board 5V SCM Control Drive LED Module

Product Parameters:A single module can drive an 8 x 8 common negative dot matrixModule working voltage: 5 VModule size: 13cm x 6.4cm x 1.3cmWith 32 fixing screw holes, hole diameter 3mmModule with input and output interface, support multiple modules cascadeWiring Instructions1. The left side of the module is the input port, and the right side is the output port.2. When controlling a single module, only need to connect the input port to the CPU3. When multiple modules are cascaded, the input terminal of the first module is connected to the CPU, the output terminal is connected to the input terminal of the second module, the output terminal of the second module is connected to the input terminal of the third module.Instruction Manual:Take 51 microcontroller as an example:VCC: 5VGND: GNDDIN: P2.2CS: P2.1CLK: P2.0Package Includes:5x MAX7219 Dot Matrix Module

• Highly Integrated Driver: This MAX7219 IC allows you to drive up to 64 individual LEDs or an 8-digit 7-segment display using just 3 general-purpose I/O pins, making it ideal for compact and efficient embedded projects.
• Flexible Brightness Control: With both analog and digital brightness adjustment options, you can easily customize the LED output intensity to suit your applicationx's lighting conditions.
• Supports Cascading: Connect multiple MAX7219 modules together to create larger LED arrays or multi-digit displays without increasing the number of microcontroller pins used.
• Low Power: Features include a 150?A low-power shutdown mode, BCD encoding support, and a scan limit register for flexible display control¡ªperfect for hobbyists, engineers, and DIY enthusiasts.
• Note: No flashing when dot matrix display! Support cascading!
