4 in 1 Dot Matrix Module (MAX7219)
The MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces micro-controllers to LED matrices. All common micro-controllers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Only one external register is used to set the segment current of each LED.
A single module can drive an 8x8 dot matrix common cathode Operating Voltage: 5V Dimensions: 12.8X12.8X1.3cm Fixing screws with 64 holes with a diameter of 3mm.
A convenient four-wire serial interface can be connected to all general-purpose microprocessors. Each data can be addressed in the update do not need to rewrite all of the display. MAX7219 also allows each user to select a data coding or non-coding. The entire device contains a 150μA low-power shutdown mode, analog, and digital brightness control, a scan-limit register that allows the user to display data bits 1-8, and one for all LED luminescence detection modes.
- The left side of the module to the input port, the right to an output port
- When the control of a single module, simply input port connected to the CPU
- When a plurality of cascaded modules, input and output termination CPU, an input terminal of the second output end of the first module a module, the first two modules of the input terminal of the three termination modules, and so on.
