Stackable Pin Header 1×4 (4-Pin) — 2.54mm, 2-Pack

Stackable Pin Header 1×4 (4-Pin) — 2.54mm, 2-Pack

Stackable 2.54mm pitch pin headers in 1×4 (4-pin) configuration — pack of 2. Stackable headers feature a female socket on top and extended male pins below — allowing multiple Arduino shields to be stacked on top of each other while maintaining electrical connections through all layers. The extended male pins pass through the shield PCB and into the Arduino or lower shield, while the female socket on top accepts the next shield in the stack.

Key Specifications

• Configuration: 1×4 (4-pin, single row) | Pitch: 2.54mm
• Type: Stackable (female socket + extended male pins)
• Contact: Tin-plated brass
• Current: 3A per pin | Voltage: 250V
• Pack: 2 headers
• Compliance: RoHS compliant

Why Stackable Headers?

• ✅ Multi-shield stacking — stack multiple Arduino shields without losing access to any pins
• ✅ Female socket on top — accepts the next shield or jumper wires for probing
• ✅ Extended male pins — pass through the shield PCB to connect to Arduino below
• ✅ Probe-friendly — female socket allows oscilloscope and multimeter probing of any pin

Typical Applications

• Arduino shield multi-layer stacking
• I2C module 4-pin stackable connector (VCC/GND/SDA/SCL)
• Probe-accessible pin header for debugging
• Custom PCB stackable interface connector
