AI Overview
If you meant Raspberry Pi 40-pin GPIO (2x20, 2.54mm pitch) headers, these are the best fits:
Raspberry Pi 2x20 (40-pin) GPIO headers
- Standard 2x20 male header (great for Pi Zero or any board needing a through-hole GPIO header): Raspberry Pi GPIO Male Header - 2x20 ($1.55)
- Keyed/polarised boxed (shrouded) 2x20 for ribbon-cable style connections: Raspberry Pi GPIO Shrouded Header - 2x20 ($2.15)
- Stacking/extra-tall 2x20 female for HAT stacking/clearance:
- Low-profile HAT headers:
- Through-hole short female: GPIO Header for Raspberry Pi HAT - 2x20 Short Female Header ($4.20)
- SMT short female: SMT GPIO Header for Raspberry Pi HAT - 2x20 Short Female Header ($3.90)
- Extra reach/clearance female headers (extended height options):
Single-row “40-pin” breakaway strips (not 2x20)
If you meant one row of 40 pins (common for Arduino/prototyping), these are 2.54mm pitch breakaway strips:
- Arduino Male Pin Headers | 0.1 (2.54 mm) Straight Black ($3.75)
- Longer pins: 40 Pin Break Away Male Header- Long Straight-10 Pcs ($4.75)
- Right-angle: 40 Pin Break Away Male Header- Right Angle-10 Pcs ($3.75)
- Single-row female strip: 40 Pin Female Header Strip ($1.55)
Related (if you’re extending the Pi’s 40-pin header)
- 40-pin GPIO extender cable (2x20 to 2x20): 40 Pin GPIO Extension Cable for any 2x20 Pin Raspberry Pi - 150mm / 6 long ($7.00)
- Breakout/extension kit: GPIO Kit for Raspberry Pi Model B+ ($5.85)
(For completeness, if you meant jumper shunts rather than headers: 40 Pin Dual In-Line (DIL) / Jumpers ($2.30))
