Assembly required! Build a 56 LED text message display. The SMT Blinky Grid is a surface mount kit. It requires different skills than through-hole soldering, but many things are the same.
The Blinky Grid usually takes between 45 minutes and 2 hours to assemble.
To construct a Blinky Grid you’ll need the kit (what you are looking at here), a soldering iron and solder, tweezers, and a CR2302 battery. Flux and solder wick are extremely useful.
