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.

Intro: 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 max721 Chip
4. Welding the electrolytic capacitor
5. Welding the pin header
6. Assembling the PCB 9Pay attention to the connection of jump cap)
7. Setup the Dot Matrix
8. Wire Connection
9. Power the Dot Matrix and testing with our Code
Components & Tools
Main chip: MAX7219
MCU: STM8S003F3
Tools:
Soldering Iron
Tweezer
Power Module
STM8S003F3P6 Development Board
ST-Link
Dupont Line
Copper Wire
Electrician Glue
Soldering Wire
Pin Header
Step 1: Step1: The 16pcs of MAX7219 Dot Matrix Kits are ready
If you'd like to do the same sign, you need to prepare 16pcs of the kits.
As the item is with STM8S003F3 MUC which the data storge space is 1K.
If you need to show more characters which is up to 1K, you can change the MCU which is with larger space. And please be noted that the MCU and Display Module
should be powered seperately.

3. Step 2: Step2: Decomposition the pin header
When the kits are ready, let's unpack the package and start the decomposition the pin header.
Step 3: Step3: Welding the SMD and max721 Chip
When you're soldering the SMD components, it's better to melt a little solder on the pad before placing components to the melting point of the solder.
1. Fixing one pin
Melting soldering tin on the pin in order to let the soldering tin are fully with the welding plate
2. Putting up the module and keeping it with an inclination of about 100°, in order to prevent the soldering tin dripping to the unwelded plate with the resulting of blockage)
3. Moving the soldering Iron slowly from the top of the soldering iron to the down (be slowly or missing solder)
4. The solder will automatically fall down due to the gravity. One side of the pins has been successfully welded when the iron moves to the bottom side. Then weld the
other side with the same method.
Please double check there is the missing solder place or not.

4. Step 4: Step4: Welding the electrolytic capacitor and the pin header
Look pictures for reference
Step 5: Step5: Assembling the PCB
Pay attention to the connection of jump cap.

5. Step 6: Step5:Setup the Dot Matrix
The side with character of the Dot Matrix should be at the same side of PCB with the character of LED_Dot8*8.
Image Notes
1. at the same side
Step 7: Step6:Wire Connection
Blue Wire - CLK
Purpule Wire - CS
Grey Wire - DIN
White Wire - GND
Black Wire - VCC
