Description:
- A single module can drive an 8 x 8 common cathode dot matrix
- With input and output interfaces, supporting multiple module cascading
- Working voltage: 5V
- With 4 fixing screw holes, aperture 3mm
- Size: Approx. 32 x 32 x 1.3mm
Specification:
- is an integrated serial input/output common-cathode display
- driver that connects a microprocessor and an 8-bit digital 7-segment
- digital LED display. It can also be connected to a bargraph display or
- 64 individual LEDs. It includes an on-chip B-type BCD encoder, a
- multi-scan circuit, a segment word driver, and an 8*8 static RAM to
- store each data. Only one external register is used to set the segment
- current for each LED.
- A convenient four-wire serial interface can
- be connected to a general-purpose microprocessor. Each data can be
- addressed without updating all the display when updating. The
- also allows the user to choose to encode or not encode each data.
- The entire device includes a 150μA low-power shutdown mode, analog and
- digital brightness control, a scan limit register that allows the user
- to display 1-8 bits of data, and a detection mode that lets all the LEDs
- glow.
- Only need 3 IO ports to drive a dot matrix! There is no flicker in the dot matrix display! Support cascade!
- Wiring Method:
- The left side of the module is the input port and the right side is the output port
- When you control a single module, you only need to connect the input port to the CPU
- When multiple modules are cascaded, the input of the first module is connected to the CPU, the output is connected to the input of the second module, the output of the second module is connected to the input of the third module, and so on.
- Take 51 microcontroller as an example:
- VCC → 5V
- GND → GND
- DIN → P2.0
- CS → P2.1
- CLK → P2.2
