Boards are in. Here's one assembled and connected to an older Arduino via the SPI - D13, D11, D10 for SS.
And a video clip of the first LED of each the 8 columns.
I don't know what it takes to shoot a decent video of LEDs, I haven't figured it out.
Will have kit prices posted shortly.
I'll be selling them via paypal - more info will be posted here tomorrow Cross Roads Electronics.
Schematic is simple, just a MAX7219, 2 caps, resistor, and the rest is headers.
Application - there's been a bunch of topics where folks wanted to drive a bunch of individual LEDs.
One way is to gang up a bunch of shift registers - an often better way is to just a MAX7219, which is basically 8 shift registers. So I wanted to make that easier to do.
