Description

Specification:

MAX7219 is an integrated serial input/output common-cathode display drivers, which connects the microprocessor 7-segment digital LED display with 8 digits, a bar graph can also be connected monitor or 64 separate LED. On type B BCD encoder includes an on-chip, multi-channel scanning loop, segment word drive, but also an 8×8 static RAM for storing each data. Only one external register is used to set the segment current for each LED.

A convenient four-wire serial interface can connect all common microprocessors. Each data can be addressed in the update does not overwrite all of the display . MAX7219 also allows the user to select each of the data code or not coded.
The entire device includes a 150A low-power shutdown mode, analog, and digital brightness control, a scan-limit register allows the user to 1-8 bits of data, there is an LED light so that all the detection mode.

Requires only three IO ports can drive a dot! No flashing dot matrix display! Support cascade!

Module Parameters:

1. A single module can drive a common cathode 8 * 8 dot matrix
2. Module Operating voltage: 5V
3. Module size : 5 cm X 3.2 cm wide X 1.5 cm high
4. Holes with four screws, diameter 3mm, can be fixed by using our M3 studs
5. Modules with input and output interfaces, support for cascading multiple modules

Wiring:

1. The left block is an input port, an output port on the right.
2. When control of a single module, simply input port receiving CPU

Package Contains:   1 x Matrix Module, 1 x connector wire
