Unlock New Capabilities

• Past Projects If you’ve already experimented with basic breadboard circuits, single-row male headers, or basic jumper wire connections, you already understand how through-hole headers provide reliable board-to-board interconnects — which means you are perfectly ready to build permanent, high-density dual-row expansion interfaces for your custom PCB layouts.
• Feature Upgrade This 40x2 Straight Male Berg Header Pin strip unlocks rigid, multi-channel power and signal distribution across your custom electronics projects. It enables you to assemble custom Raspberry Pi GPIO expansion breakouts, construct multi-pin ribbon cable interfaces, create stackable Arduino shield headers, and organize clean multi-sensor power buses on custom prototyping boards without messy, loose wiring.
• Effort Level: Beginner (Requires basic through-hole soldering)

Minimum hardware to get started:

• Soldering Station / Soldering Iron: required because through-hole header pins must be soldered permanently to PCB pads to establish durable electrical contact.
• Rosin Core Solder Wire: required to form high-conductivity, mechanically strong solder joints around each through-hole leg.
• Flush Cutters / Diagonal Pliers: required to snap or clip the 40x2 pin strip down to smaller custom lengths (such as 2x5, 2x10, or 2x20) safely without cracking the plastic body.

Included in the Box:

• 1× 40x2 Dual Row Male Berg Header Pin Strip

Frequently Asked Questions

• Are these straight male Berg header pins compatible with standard 2.54mm (0.1") breadboards and perfboards?
  Yes, the pin pitch is exactly 2.54mm (0.1 inch), making them fully compatible with standard breadboard holes, perfboards, and 2.54mm female sockets.
• Can I use this 40x2 straight header on a Raspberry Pi GPIO port?
  Yes, the 2x40 pin configuration matches the 40-pin GPIO footprint of the Raspberry Pi, allowing you to build expansion HATs or custom breakouts.
• Will these straight male pins mate directly with female jumper wires?
  Yes, standard 2.54mm female jumper wires fit securely over the top male pins for quick prototyping and signal testing.
• Is this 40x2 header compatible with ribbon cable IDC connectors?
  Yes, standard 80-pin / 40x2 female IDC socket connectors mate directly with these 2.54mm pitch dual-row straight pins.
• What is the maximum current rating per pin for this 40x2 header strip?
  Each individual pin is rated to handle up to 3A DC continuous current under normal ambient operating conditions.
• What is the maximum voltage rating for these header pins?
  The insulator and contact spacing are rated for a dielectric withstand voltage of up to 250V AC/DC.
• Can I pass high-current motor power through these straight Berg headers?
  While single pins handle up to 3A, high-power loads above 3A should use multiple parallel pins or heavy-duty screw terminal blocks to avoid resistive heating.
• How do I snap or cut a 40x2 pin header down to a smaller pin count?
  You can easily score the plastic insulator housing between pin pairs with a utility knife or clip cleanly using sharp electronic flush cutters.
• Which pin legs go through the PCB holes during soldering?
  The shorter bottom pins pass through the PCB through-holes for soldering, while the longer top vertical pins extend upward to receive female connectors.
• Does the plastic insulator melt during normal soldering?
  The black housing is molded from high-temperature thermoplastic (UL94V-0); however, you should avoid applying a hot soldering iron directly to a single pin for more than 3 to 4 seconds.
• Do I need any software libraries to use these header pins?
  No, header pins are passive mechanical interconnects and do not require any software libraries or code configuration.
• Can I use straight Berg headers for I2C and SPI bus signals?
  Yes, straight male headers provide excellent low-impedance electrical pathways for high-speed digital signals including SPI, I2C, UART, and PWM.
• How do I label pinout functions on custom straight header projects?
  You can print signal labels on silkscreen layers during PCB design or stick printed pinout diagram tape onto the plastic insulator body.
