The Adafruit Shield Compatibility Guide now literally goes to eleven: alongside the original five shields are details for six more: the Ultimate GPS Logger Shield, Wave Shield, LCD Shield w/16×2 Character Display, CC3000 WiFi Shield, 2.8″ TFT Touch Shield and 1.8″ TFT Shield w/Joystick. Pin usage, links to libraries and tutorials, it’s all there!
Arduino shields are splendid in concept…but, as new Arduino variants mutate and evolve, one inevitably runs into the issue that each board has its own distinct personality, and just following the shield pinout is no longer a guarantee of interoperability.
Our new guide aims to clear up this confusion. It’s a one-stop cross-reference with each combination of Adafruit shield and Arduino board, finding workarounds where incompatibilities exist and improving our library code along the way.
We have five Adafruit shields to start with: PWM/Servo Shield, Assembled Data Logging Shield, Motor/Stepper/Servo Shield, NeoPixel Shield and the PN532 NFC/RFID Shield, and we have these working across all the mainstream Arduino boards: Uno, Leonardo, Mega (all variants), even the Due! More shields will be added incrementally until the whole stable is represented.
