These boards make it impossible to stack another shield directly on top of them.
- SFE Xbee
- SFE Joystick Shield
- Seeed Danger Shield
- Seed XBee shield v1.1
- Liquidware TouchShield
- Liquidware TouchShield Stealth
- Liquidware input shield
- CID LCD TFT
I could not figure out which pins these shields use:
- ButtonPad seems to only be useful on Arduino Mega boards.
