The TK52 at an angle: an 8 by 8 LED matrix standing as a thick square block over most of a black board, and in front of it a strip of board with two round mounting holes and a right-angle six-pin header printed GND, VCC, CS, DIN, NC and CLK.

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.

Every pin and part: the six-pin header with NC on nothing and no DOUT, and under the matrix the MAX7219, R7 that sets the LED current, and the supply capacitor.
