Author:ICStation    ICStation.comwww.ICStation.com is one-stop store of electronic, which specializes in all kinds of IC products, such IC accessories, Module, Robots, Development Board,Transistor, Capacitor and so on. We're located in Shenzhen, China. Benefiting from local manufacture and very convenient global logistic system, ourproducts with high quality, reasonable price and broad product line.

Intro:  DIY LED Sign with MAX7219 Dot Matrix Module STM8S003F3 MCUTo 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 cannot 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 ready2. Decomposition the pin header3. Welding the SMD and max721 Chip4. Welding the electrolytic capacitor5. Welding the pin header6. Assembling the PCB 9Pay attention to the connection of jump cap)7. Setup the Dot Matrix8. Wire Connection9. Power the Dot Matrix and testing with our Code

Components & Tools

Main chip: MAX7219MCU: STM8S003F3Tools:Soldering Iron

Tweezer

Step 1: Step1: The 16pcs of MAX7219 Dot Matrix Kits are readyIf 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 Moduleshould be powered seperately.

Step 2: Step2: Decomposition the pin headerWhen the kits are ready, let's unpack the package and start the decomposition the pin header.

Step 3: Step3: Welding the SMD and max721 ChipWhen 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 pinMelting 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 theother side with the same method.

Please double check there is the missing solder place or not.
