DIY LED Sign with MAX7219 Dot Matrix Module STM8S003F3 MCU

To satisfy electronic DIY hobbyists, ICStation has developed MAX7219 Dot Matrix Module. It uses the Max7219 chip which do a great job on saving of MCU I/O. It can not only control each point individually, but also can be extended without limitation to meet your requirements on LED Sign, Team Logo and so on.
What's more, it's controlled by the STM8S003F3 MCU with 1K data storge space which is low cost, low power consumption, very powerful.

Major Building Portions of the electronic DIY kits:
1. The 16pcs of MAX7219 Dot Matrix Kits are ready
2. Decomposition the pin header
3. Welding the SMD and max7219 Chip
4. Welding the electrolytic capacitor
5. Welding the pin header

MAX7219 Dot Matrix MCU Control Display Module DIY Kit for Arduino

Module parameters:
1.A single module can drive an 8 * 8 common cathode lattice
2.Module Operating voltage: 5V.
3.Module size: 5 cm long X 3.2 cm wide X 1.5 cm high
4.With four screws hole, aperture 3mm, by using our M3 Tongzhu fixed
5.Module with input and output interfaces, supports multiple modules cascade

Wiring instructions:
1.The module left as an input port to the output port on the right.
2.The control of a single module, simply input port to the CPU
3.Multiple modules cascade input termination CPU, 2 output termination module, a module of the input of the input terminal, the output terminal of the first two modules of the first three modules, and so on ... 

51 MCU, for example:
VCC → 5V
GND → GND
DIN → P22
CS → P21
CLK → P20

MAX7219 Dot Matrix Module Control Display Module DIY kit Cascade - Designed by ICStation.com

MAX7219 Dot Matrix Module Control Display Module DIY kit Cascade

Product Feature:

• Seamless splicing and so that the dot matrix can be flexible spliced .
• Common cathode with bright dot matrix(8*8), display fresh and brilliant picture.
• A screen roll freely, to achieve the perfect picture display
• Since the master chip is used in Max7219 to make product have the following characteristics:

1).The transmission efficiency of up to 10MHz.
2).Can be individually controlled for each point.
3).Lowest power consumption of 450uA (one module).
4).Power-on reset automatically display full black
5).Serial communication, a great saving of MCU I/O, also can be extended To expand the program with SPI.
6).For each screen brightness control, by setting the Max7219 instructions.  

Ⅱ.Application: Education,DIY, Robot,etc.

Ⅲ.ABSOLUTE MAXIMUM RATINGS

• Voltage (with respect to GND) V+: -0.3V to 6V
• DIN, CLK, LOAD, CS: -0.3V to 6V Current
• DIG0-DIG7 Sink Curr: 500mA
• SEGA-G, DP Source Current: 100mA
• Continuous Power Dissipation (TA=+85°C) Narrow Plastic DIP: 0.87W
• Wide SO: 0.76W
• Narrow CERDIP: 1.1W
• Operating Temperature Ranges(Max7219) MAX7219: 0°C to +70°C
• Storage Temperature Range: -65°C to +160°C
• Lead Temperature (soldering, 10sec): +300°C 

Ⅳ.PIN Define

• CLK: Serial-Clock Input. 10MHz maximum rate.
• CS: Chip-Select Input. Serial data is loaded into the shift register while CS is low.
• DIN: Serial-Data Input. Data is loaded into the internal 16-bit shift register on CLK´s rising edge
• DOUT: Serial-Data Output. The data into DIN is valid at DOUT 16.5 clock cycles later.
• VCC: Positive Supply Voltage. Connect to +5V.
