I recently purchased the Mega 2560 (A000067) and the proto board kit (A00081). It seems like the proto board kit doesn't have enough headers for the Mega, it includes 40x1, 3x2 and 18x2. It seems like the Mega has 50 - 5 x 8x1 and 1 x 10x1, along with the 18x2. I'm not sure what the 3x2 is used for, perhaps the ICSP? It doesn't mate with the ICSP header on the Mega board, that is pins, not sockets.
Am I missing something?
Thanks!
