2.54mm 1×40 Pin Male & Female Header Connector Kit — 5PCS Breakaway Pin Strip

The 2.54mm pitch 1×40 pin header is the most versatile connector in any electronics maker’s toolkit. Break it to any length from 1 to 40 pins, solder it to any PCB, and instantly create reliable, solderable connections for Arduino shields, sensor modules, breadboard adapters, and custom PCB designs. This kit includes both male and female variants so you can build complete mating connector pairs for your projects.

Why 2.54mm Headers Are Essential

✅ Universal 0.1″ pitch standard — compatible with Arduino, Raspberry Pi, breadboards, and virtually all hobbyist PCBs
✅ Breakaway design — snap to any pin count from 1 to 40 with pliers or a sharp knife
✅ Male + female included — create complete mating pairs for detachable module connections
✅ Solderable through-hole — secure, low-resistance solder joints for reliable connections
✅ Tin-plated copper pins — excellent conductivity and solderability
✅ Heat-resistant nylon housing — withstands soldering iron temperatures without deforming
✅ 5PCS per type — enough for multiple projects in one pack

Common Applications

Arduino Uno, Mega, Nano shield connectors
Raspberry Pi GPIO header extensions
Sensor module PCB connections (DHT22, HC-SR04, MPU6050, etc.)
Breadboard-to-PCB adapter connections
Custom PCB prototyping and development boards
JTAG, SWD, and ISP programming headers
LCD and OLED display module connections
3D printer control board connectors

How to Use

Determine pin count needed for your application (e.g., 6 pins for Arduino ICSP header).
Score and snap the 40-pin strip at the desired position using pliers or a sharp blade.
Insert into PCB holes — male pins go through from the component side, female sockets from the component side.
Solder each pin on the solder side of the PCB using a fine-tip soldering iron at 300–350°C.
Mate connectors — press male and female headers together for a secure, detachable connection.
