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.

Sixty-four LEDs and a MAX7219 that scans them for you. Two boards share this page — the TinkerBlock TK52 and the chainable module that comes three to a box — and only one of them can be chained.
