LED board
Spencer's LED matrix is quite impressive because it enables you to show all the different animations that you can program in CircuitBlocks.
Do you want to guess how many LED lights are there on the board? (scroll down to find the answer)
There is still that cool design on the back of the board:
Spencer's LED grid consists of 144 small LED lights that light up depending on your chosen animation or Spencer's answer to your command.
This particular model of the lights is called HL-AM-2835H489W-S1-08HL-HR3.
The small component that's pointed in the photo is the LED driver called IS31FL37.
