ARMinARM Caps

Caps are addons for the ARMinARM board. They plug into the female headers with one 2x25 and one 1x25 male header.

Protocap Wide has 21x33 (693) holes.
Protocap Narrow has 21x25 (525) holes.

Please note that all pins align on a 0.1" grid. Any piece of protoboard with male pins will fit on the ARMinARM board. The protocaps just fit nicely.

There's still access to the USB and JTAG pins on the bottom of the ARMinARM board with a cap on. If you think you're going to need them often, you might want to consider soldering 90 degrees bent pins on there.
