Your shield won't stack on the next one, and you're stuck soldering a fresh breakout just to add a sensor. Sorted. This stackable header set drops straight onto your Arduino or Duinotech-compatible board and gives you male-to-female stacking in seconds. Need female headers instead? Snip the pins back and you've got them. The set covers every pin count you'll hit on a standard board: one 10-pin, two 8-pin, one 6-pin, and one 2×3-pin for your ICSP header. No hunting through five different packs. Pop them in, stack your next shield, keep building
