Could someone provide me the pin mapping for Seeeduino V2.21? The schematic provided http://garden.seeedstudio.com/images/0/09/Seeeduino_v2.21.pdf
doesn't refer which one is which.
"Seeeduino is Arduino compatible board. Its design is based on Diecimila scheme, 100% compatible to its existing program, shield and IDEs. On the hardware part, remarkable changes are taken to improve the flexibility and user experience." -According to the schematic provided you can no longer use the test LED "L" as you'd use in Diecimila. It seems you'd have to power pin 13 externally to drive the LED instead of programming pin 13 as HIGH.
