The GPIO reference card frees you from the complexities associated with the GPIO connections. Having the GPIO Reference Card means that you don’t have to memorize the complex GPIO chart.

GPIO Reference Card Features

• The reference card is idiot-proof (there is no way for backward plugging as the card fits only from the right side)
• Easy to handle
• You can easily judge if the cables are connected the right way
• The pins have been categorized (I2C/UART/Power/IO) so it becomes easier to identify the connection type
• Slide the card over the GOPI header and its ready to work. Super easy installation!

Once installed properly on the header, the card leaves enough space to accommodate the cable heads. When setting it up, the card actually pushes downwards and the header holds it tightly. The markings on the pitch signify the pin-function. The values are clear to read so there is no room for any misunderstanding. You need to have one of these cards for quick and reliable connections.
