MAX7219 8x8 Dot Led Matrix Display Module
memory Technical Parameters & Datasheet Summary
SKU: Anil506The MAX7219 8x8 Dot Led Matrix Display Module is an integrated serial input / output common-cathode display driver, it is connected to a microprocessor with 8-digit 7-segment digital LED display can also be connected to the bar graph display or 64 separate LED. On B BCD encoder including an on-chip, multi-channel scanning loop word drive, but also an 8 x 8 static RAM is used to store each data. Only one external register is used to set the current of each LED segment.
A convenient four-wire serial interface can connect all general-purpose microprocessor. Each data can be addressed in the update does not need to rewrite all the display. MAX7219 also allows the user to select on each data coding or non-coding.
The entire device contains a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display the 1-8 bits of data, as well as a let all LED light detection mode.
Only need three IO ports can drive a dot-matrix! Dot-matrix display, flicker-free! Supports cascading!
Features :
- Requires only 3 communication wires of MCU
- Cascading multiple Matrix LED Module is very easy
- Size of the display is very compact
- The PCB features M3 holes for mounting.
