Gold-finish board with female socket and two 2x20 male headers

LORDWORLD

LORDWORLD Dual GPIO Expander for Raspberry Pi Pico, 2x20 Male Headers

SKU CH-GNG4-H5CDA

Adds two sets of 2x20 male headers with clear pinout labels and immersion gold finish for connecting multiple Pico expansion modules

  • Standard Pico female header accepts Pi Pico directly or via jumper wires
  • Two sets of 2x20 male headers connect multiple expansion modules
  • Clear pinout labels on front side simplify wiring
  • Immersion gold finish protects contacts and improves appearance
  • Compact edge-device form factor fits maker projects

Dual GPIO Expander for Pi Pico

The LORDWORLD board adds two 2x20 male header sets to a Raspberry Pi Pico. It targets makers who need more connection points for expansion modules. A standard Pico female header is included for direct attachment when the Pico has male pins soldered. Jumper wires can also be used for flexible wiring.

Thermals noise and power draw

The expander is a passive PCB with no active components, so it generates no heat and produces no noise. It draws no power of its own and adds negligible load to the Pico supply. The immersion gold finish protects contacts without affecting electrical performance.

Build integration and freedoms

Clear pinout labels on the front side simplify wiring and reduce assembly errors. The dual header layout frees developers from stacking constraints by exposing every Pico pin twice. Buyers who need a compact single-header adapter or on-board level shifting will not find those features here.

Questions about this item

How do I attach the Raspberry Pi Pico to the female header and what step is often missed?

Solder male headers onto the Pico first, then press it into the female socket; the step often missed is soldering the Pico's own headers before mounting.

Will the gold-finish male headers need cleaning or replacement over time?

The immersion gold finish resists oxidation, so the 2x20 male headers typically need no cleaning or replacement during normal use.

How many expansion modules can I connect simultaneously using the two header sets?

The board provides two sets of 2x20 male headers, allowing two expansion modules to be plugged in at the same time.
