The MAX7219 is an integrated serial input / output common-cathode display driver, it is connected to a microprocessor with 8-digit 7-segment digital LED display that 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 microprocessors. 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 150 μA low-power shutdown mode, analog, and digital brightness control, a scan-limit register that 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!
This price is the price of the DIY kit, not a finished product price!
Disclaimer: All components are brand new, PCB board after all the test stand test to ensure the physical well-connected. The welded risk once welding does not accept returns. But can help customers free commissioning, repair, return shipping costs borne by the customer !!
Module parameters:
A single module can drive an 8 * 8 common cathode lattice
2 module operating voltage: 5V
Module size: 5 cm in length X width 3.2 cm x 1.5 cm
4 with four screws hole, aperture 3mm, Our M3 Tongzhu fixed
5 modules with input and output interface, supports multiple modules cascade
Wiring instructions:
The module on the left is an input port, output port on the right.
Control of a single module, simply input port to the CPU
3 more modules cascade input termination module of a CPU, 2 output termination module input and output of the two modules is terminated with the input end of the first three modules, and so on.
51 MCU, for example:
VCC → 5V
GND → GND
DIN → P22
CS → P21
CLK → P20
Shipping list:
1 * MAX7219 dot matrix module (finished with dot matrix, have been tested well)
1 * DuPont line
