I've got 3 spare Afterglow Nanos from a recent build.
For those that don't know what they are
https://github.com/bitfieldlabs/afterglow
These are v1.5, which take the 18V directly from the rows/cols, so no need for the dodgy power croc clip anymore.
Price per board is £45 plus delivery. This includes the board, fuses, and Arduino Nano (with firmware) - but you will need to sort out the cabling.
