Unlock New Capabilities

• Past Projects If you’ve already experimented with basic breadboard prototyping, single-row female sockets, or standard straight headers on Arduino shields, you already understand how through-hole headers establish reliable board-to-board sockets — which means you are perfectly ready to build low-profile, right-angle female interconnects for custom enclosures.
• Feature Upgrade This 40x2 Right Angle Female Berg Header Socket strip unlocks horizontal, space-saving board-to-board mating across your custom electronics builds. It enables you to mount side-entry daughterboards, route dual-row ribbon cables parallel to your PCB, create low-profile Raspberry Pi HAT expansion sockets, and fit dense multi-board stacks inside slim project boxes without vertical clearance issues.
• Effort Level: Beginner (Requires basic through-hole soldering)

Minimum hardware to get started:

• Soldering Station / Soldering Iron: required because through-hole socket pins must be soldered cleanly into PCB pads to establish durable electrical and mechanical contact.
• Rosin Core Solder Wire: required to create high-conductivity, solid solder joints around each 90-degree pin leg.
• Flush Cutters / Diagonal Pliers: required to snap or trim the 40x2 socket strip down to smaller custom lengths (such as 2x5, 2x10, or 2x20) cleanly without cracking the insulator body.

Frequently Asked Questions

• Are these right-angle female Berg header sockets compatible with standard 2.54mm (0.1") male pins?
  Yes, the socket pitch is exactly 2.54mm (0.1 inch), making them fully compatible with standard 2.54mm male headers, breakaway pins, and jumper cables.
• Can I use this 40x2 right-angle female socket on a Raspberry Pi GPIO connector?
  Yes, the 2x40 socket configuration matches the 40-pin GPIO footprint of the Raspberry Pi, allowing you to convert vertical Pi GPIO headers into side-facing horizontal connections.
• Will these right-angle female sockets mate directly with male jumper wires?
  Yes, standard 2.54mm male jumper wires insert securely into these female contact sockets for fast signal testing and prototyping.
• Is this 40x2 right-angle socket compatible with ribbon cable male connectors?
  Yes, standard 80-pin / 40x2 male ribbon cable connectors and shrouded headers mate directly with these 2.54mm pitch dual-row right-angle sockets.
• What is the maximum current rating per contact for this 40x2 female socket header?
  Each individual phosphor bronze contact socket is rated to handle up to 3A DC continuous current under normal ambient operating conditions.
• What is the maximum voltage rating for these female header sockets?
  The insulator housing and contact spacing are rated for a dielectric withstand voltage of up to 250V AC/DC.
• Can I pass power rails through these right-angle female sockets?
  Yes, power rails can be safely passed through these sockets, but continuous loads above 3A should be distributed across multiple parallel contacts.
• How do I snap or cut a 40x2 female header socket down to a smaller pin count?
  You can easily score the plastic insulator housing between socket pairs with a utility knife or clip cleanly using sharp electronic flush cutters.
• Which side of the right-angle socket goes through the PCB for soldering?
  The short 90-degree bent solder legs pass through the PCB through-holes, while the horizontal socket openings face outward parallel to the board.
• Does the plastic insulator body 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 leg for more than 3 to 4 seconds.
• Do I need any software libraries to use these female header sockets?
  No, header sockets are passive mechanical interconnects and do not require any software libraries or code configuration.
• Can I use right-angle female sockets for high-speed digital signals like SPI and I2C?
  Yes, these gold-flash plated phosphor bronze contacts provide excellent low-impedance electrical pathways for high-speed digital signals including SPI, I2C, UART, and PWM.
