This is based on Warren Brayshaw’s post here, which seems to have the A0-A7 lines reversed (compared with the Nano V3 . Maybe it once was correct for an earlier version of the Nano – I don’t know). The library below has been updated to be consistent with V3. The ICSP headers are not included, just the headers on the long sides of the nano board.
