Pico - Dual-Expander IC Test Board

This is a dual GPIO expander designed specifically for the Raspberry Pi Pico. It comes with two sets of standard Raspberry Pi Pico GPIO male headers. The board features a standard Raspberry Pi Pico female header, which allows you to directly attach the Raspberry Pi Pico if a male header is soldered, or you can use jumper wires. With two sets of 2x20 male headers, you can connect more Raspberry Pi Pico expansion modules. The front side has clear pinout labels, making it very easy to use. It uses an immersion gold process, which not only looks beautiful but is also practical, giving it a stunning aesthetic appearance. The center female pin header is for directly attaching the Raspberry Pi Pico. Remember to check for pin conflicts between the modules you want to use together before connecting. Note that the Raspberry Pi Pico and expansion modules are not included. The board has a black base panel, white pinout labels, and a golden rounded outline, creating a visually appealing look.

Using this Pico dual GPIO expander is straightforward. First, if you've soldered a male header, you can directly attach the Raspberry Pi Pico to the standard female header on the board. Otherwise, use jumper wires to connect them. The two sets of 2x20 male headers are there for you to connect more expansion modules. Before connecting any modules, make sure to check for pin conflicts to avoid any issues. As for maintenance, keep the board clean and dry. Avoid exposing it to extreme temperatures or moisture. If there's dust on the board, you can use a soft brush to gently clean it. Remember, the Raspberry Pi Pico and expansion modules are not part of this product, so you'll need to get them separately.
