Pzsmocn IO Expansion Board Compatible with Raspberry Pi-3, Pi-4 and Pi-400. with 40 Pin Contrast Silk Screen, BCM Encoding Information, WiringPi Encoding Information and Color GPIO 40 Pin Cable.

• The expansion board draws out the IO ports of the Raspberry Pi one by one, and provides a 40-pin pin control silkscreen.
• The pin comparison silkscreen contains detailed BCM code and WiringPi code comparison information for Raspberry Pi.
• The expansion board is perfectly compatible with Raspberry Pi 3 and Raspberry Pi 4.
• The expansion board and color GPIO 40-pin cable are compatible with Raspberry Pi 400.
• It saves you the trouble of frequently checking the pin comparison table when programming with Raspberry Pi, protects your project and saves precious time.

For beginners, Python programming is required when learning and completing Raspberry Pi projects. We can often consult the pin assignment table to find out the BCM code information and WiringPi code information corresponding to the relevant GPIO. This process is cumbersome and ineffective. In order to solve this problem, we designed a Raspberry Pi expansion board with detailed information on the pin assignment table. This IO expansion board is specially developed for Raspberry Pi and is perfectly compatible with Raspberry Pi 3, Raspberry Pi 4 and Raspberry Pi 400. We will show all Raspberry Pi IO interface information tables one by one. Most importantly, the expansion board provides 40-pin comparison screen printing, which contains detailed BCM encoding information and WiringPi encoding information, which saves you from having to frequently check the pin comparison chart when programming with Raspberry Pi, and saves your project. precious time.
