Pin Usage

• SPI
  • Slave select (SS) : Arduino pin 10 (port B, pin 2)
  • Clock (SCK) : Arduino pin 13 (port B, pin 5)
  • Master in, slave out (MISO) : Arduino pin 12 (port B, pin 4)
  • Master out, slave in (MOSI) : Arduino pin 11 (port B, pin 3)
• Interrupt (Uses only one of the following, depending on jumper setting)
  • INT0 : Arduino pin 2 (port D, pin 2)
  • DIG8 : Arduino pin 8 (port B, pin 0)
• LED : Arduino pin 9 (port B, pin 1)
  • To regain use of this pin, remove the LED jumper cap
• 5V power
• GND
