Most Arduino shields use regular “male” pin headers for connection to the Arduino, but by using stackable headers instead you can stack shields on top of each other and use multiple shields at the same time.
Of course, you need to make sure each of the shields uses different I/O pins on your Arduino!
We supply the stackable headers in a pack to suit Arduino shields with the latest “R3” headers:
- 1 × 10-pin
- 2 × 8-pin
- 1 x 6-pin
- 1 x 2×3-pin (for ICSP)
