Dot Matrix LED Display, Chain Kit, Max7219 [Set]

Description RA modularized LED matrix display, you can connect as much as you can to make a big sliding display. Easy to assemble and connect in a flexible way. Supported by arduino library called “parola” as we know, this is also a hardware redesign, and there should be more available demo code you can find on internet or develop yourself. A kit includes all the parts in the main image, and this is the price for one kit. When you connect more than 12 modules in one chain, you should concern provide a external high current power instead of the power from arduino, since the arduino can hardly afford this anymore. Module size 3.2 * 3.2 CM Update: From 2016-12-08, this changed to 2 sets or 3 sets, the PCB are pre connected, no need to soldering the pins and add jumper in the between, save a lot of work, elimiate error, and much better physical strength. You can make 2 set or 3 set directly, or any combination like 2 3, 3 3 chained. Add a few glue on the few jumpers will make the chained display perfectly fixed. Package includes: 2 or 3 pcs Boards presoldered SMD parts, 2 or 3 pcs 3mm dia. dot matrix display 2pcs 1x5pin 0.1” pin header (chain connection) 2 or 3 pcs 1x8pin 0.1” pin header (optionally for dot matrix socket) 1pcs bended 1×5 0.1”pin header (for wiring) 5 jumpers (chain connection)   Documentation please see on this page.
