The image below shows a Pi 3 in the enclosure. The height of the enclosure and PCB varies depending on the design. The extension header with 7.30mm pin length uses three plastic spacers which cover the pins more when using a HAT or the Pi Wedge's IDC cable.Įxtension Header with 9.80mm Pin Length is Used to Help Stack the Qwiic SHIM and Pi Servo HAT on a Pi 4 with Heat SinkĮxtension Header with 7.30mm Pin Length is Used to Help Connect the Pi Wedge's IDC Cable to the Pi 4 with Heat Sink The header can also be used to sandwich a board betwen the Pi and Pi Wedge's IDC cable.
The extension header with 9.80mm pin length is useful when sandwiching a PCB between a Pi and HAT. The SolutionĮxtension headers are also useful when stacking HAT's with other single board computers that utilize the Pi's standard 2x20 GPIO header like the Google Coral and NVIDIA Jetson. But in order to SSH to it, we need to know it's IP address.and of course, the IP address is most easily learned by running ifconfig on the command line.
We just want to SSH into it, so we can use the command line. In addition to the physical issues of using the I/O connector, getting started with a brand new Raspberry Pi B+ always seems to involve a chicken-and-egg situation. They involved a lot of "ratsnest jiggling" when things stopped working. Our first projects used a bunch of F-M jumper wires that we just plugged into the header. The pins also don't translate to a solderless breadboard very easily. Pins used for similar functions aren't always grouped together, and power and ground pins are interspersed with no obvious pattern. But the connector doesn't have detailed labeling, and the native pin arrangement is somewhat scattershot. The Raspberry Pi Model B+ has a 40-pin connector that provides access to several communication interfaces, plus GPIO and power.
