Gold-finish development board with 20 and 40 pin headers, USB power, reset button

LORDWORLD

LORDWORLD GPIO Expander Development Board 20 40 PIN

SKU CH-9VGM-FCQFM

A development board with 20-pin Pico and 40-pin Raspberry Pi headers, USB power input, reset button and labelled pinouts for connecting HATs and expansion modules

  • Direct Pico attachment via female header for quick prototyping
  • Dual 40PIN and 20PIN headers connect HATs and Pico boards
  • USB power input delivers stable current to multiple modules
  • Dedicated RESET button simplifies firmware debugging
  • Front-side pin labels and immersion gold finish aid reliable wiring

Pico Header Bridge

This board mates a Raspberry Pi Pico to standard HATs through a 20-pin Pico header and a 40-pin Raspberry Pi header. Makers who want to reuse existing Raspberry Pi add-on boards with a Pico will find the pinout labels and direct female-header attachment convenient for quick prototyping.

Steady Power Delivery

A dedicated USB power input feeds both the Pico and any attached expansion modules, preventing voltage sag when several HATs draw current simultaneously. The breakout RESET button lets developers restart the target without unplugging cables, keeping long debug sessions stable.

From Jumper Wires to HAT Stack

The board replaces loose jumper wiring between a Pico and Raspberry Pi-format peripherals, turning a fragile breadboard link into a repeatable mechanical connection. Builders who only need a single Pico-native module, or who require a different form factor, will not benefit from the dual-header layout.

Perguntas sobre este artigo

Does the USB power input on the GPIO expander keep the board cool when running all day?

The USB power input supplies enough current for multiple expansion modules, and the board has no active cooling components.

Which headers must already be soldered on my Raspberry Pi Pico for it to plug straight onto the 2×20PIN header?

A male header must be soldered to the Pico for direct attachment; otherwise jumper wires can bridge the connection.

Will a Raspberry Pi HAT with a 40PIN connector work alongside the Pico expansion header on this board?

Yes, the board provides both a standard 40PIN header for RPi HATs and a 2×20PIN header for Pico expansion boards simultaneously.
