32x8 LED Matrix with MAX7219, 3-Pack
Four 8x8 squares in one strip, 256 LEDs, three signal wires. What the pads are called, why the sketch has to say four, and what to do about a 3.3 V board on a chip that wants 3.5 V.

MAX7219 Vintage Tube LED Clock Kit
Eight 0.28-inch digits on a MAX7219, in a glass tube with a cork. Three displays arrive built and three arrive as pieces — a driver board and two four-digit panels, in red or blue, with a colon or with decimal points.

8x8 LED Matrix
Sixty-four red LEDs and a MAX7219 that scans them for you, on the TinkerBlock TK52: five wires, VCC on 5 V, a picture sent as eight bytes. The page is shared with the chainable 3-pack module, and only that one can be chained: the TK52 has no DOUT.
