✨ Professional 4-in-1 Prototyping Header Kit, 20Pack (5x4 Types) 1x40 Pin 2.54mm Gold Plated Male/Female for PCB Stacking, Arduino, Breadboard Module Interface ✨🔍 Product Overview

4-in-1 Prototyping Header System: Engineer Your Connections from Concept to Product

Tired of piecing together generic headers for every project stage? This professional-grade kit delivers the four essential 1x40 pin header variants you need to build, interface, stack, and test with confidence and speed.

Why This Curated System Beats Buying Random Parts:

• Complete Workflow Coverage: We've selected the exact headers required for permanent installation (Male Pins), display/board interfacing (Tall Female Sockets), modular docking (Standard Female Sockets), and mechanical stacking (Centered Long Pins). One kit replaces multiple SKUs.
• Accelerated Development & Debugging: Female sockets enable true hot-swapping of sensors and modules, slashing testing time. Centered Long Pins allow for prototyping complex multi-board systems with precise spacing.
• Guaranteed Compatibility & Reliability: Universal 2.54mm pitch ensures fit with all standard prototyping tools. Selective gold plating on male pins guarantees signal integrity and durability where it matters most.

Technical Specifications & Applications:

Type 1: Standard Male Pin Header (Gold-Plated Contacts)
  Specs: 1x40P, Pin Length: 6mm, Housing: 2.5mm
  Primary Use: Permanent PCB headers, GPIO pins, breadboard jumpers. Type 2: Tall Female Socket Header
  Specs: 1x40P, Pin Length: 11mm, Housing: 8.4mm
  Primary Use: Pluggable ports for LCDs, 3D Printer mainboards, or any application requiring elevated connections. Type 3: Standard Female Socket Header
  Specs: 1x40P, Pin Length: 3.3mm, Housing: 8.5mm
  Primary Use: Hot-swappable docks for sensor arrays, communication modules (Bluetooth/Wi-Fi), or prototyping shields. Type 4: Centered Long Pin Header
  Specs: 1x40P, Total Length: 15mm, Pin Length: 6.25mm per side, Housing: 2.5mm
  Primary Use: Stacking PCBs with a defined air gap, extending connections inside enclosures, or as extra-long male pins.

Ideal For Professional & Educational Environments:
Electronics Engineering Labs – Build test fixtures and modular prototypes.
University & Makerspace Courses – Teach PCB design and system integration.
Embedded Systems Developers – Interface between microcontrollers (Arduino, RPi, ESP32) and peripherals.
Product Design & R&D – Create functional prototypes with reliable, repeatable connections.

Package Includes:
5 x Standard Male Pin Header (1x40P, Gold-Plated Contacts)
5 x Tall Female Socket Header (1x40P)
5 x Standard Female Socket Header (1x40P)
5 x Centered Long Pin Header (1x40P)
All headers are individually packaged in labeled, anti-static bags for professional handling and storage.

🔥 Key Features

• 1x40 PIN HEADER SYSTEM FOR FULL DEVELOPMENT CYCLE – Includes 5 each of: Gold-Plated Male Pins (permanent install), Tall Female Sockets (11mm for displays), Standard Female Sockets (module docks), and Centered Long Pins (15mm for PCB stacking).
• DESIGNED FOR MODULARITY & HOT-SWAPPING – Quickly create pluggable interfaces for LCDs, sensor modules (DHT11, HC-SR04), wireless boards (ESP32), and 3D printer controllers. Test and replace components without soldering.
• PRECISION PCB STACKING & SPACING SOLUTION – Achieve reliable, spaced board-to-board connections for power distribution, signal isolation, or adding cooling fans between PCBs in custom enclosures or test fixtures.
• PREMIUM CONSTRUCTION FOR DEMANDING USE – Made with high-temp PA66 plastic and precision-machined pins. Gold-plated contacts on male pins provide reliable, low-resistance connections critical for analog signals and high-cycle testing.
• ENGINEERED FOR EFFICIENCY & PROTECTION – The 20 headers come systematically organized in labeled, anti-static bags. This saves time, prevents loss, and meets the organized workflow demands of labs, workshops, and professional makerspaces.
