Single-board computer · USB · Ethernet · GPIOWhat to look for
GPIO header
The two-row header connects to suitable sensors and expansion hardware. Pin function and voltage must be checked against the official pinout.
USB and Ethernet
Compare the stacked USB connectors with the Ethernet jack. They connect different kinds of peripherals and networks.
Power and display
Locate USB-C power and the small HDMI outputs along the board edge. Similar-looking connectors do not necessarily carry the same signals.
