When making Raspberry Pi projects or learning to use Raspberry Pi for python programming, we may often need to check its Pinout Table to find out the BCM and WiringPi code corresponding to the related GPIOs, which is time-consuming and inefficient. Now in order to solve this problem, we designed a Raspberry Pi expansion hat with detailed Pinout information.
This IO expansion hat, specially developed for Raspberry Pi, is perfectly compatible with Pi 3, Pi 4, and Pi 400. All IO ports of Raspberry Pi are led out one by one. Most importantly, the hat provides 40PIN comparison silkscreens that contain detailed BCM code and WPI code information, which saves the trouble of frequently checking pin comparison table when programming with Pi.
There are two ways to use the expansion board:

- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
