Hello. You can find more information about the topic here: https://www.raspberrypi.org/blog/gpio-expander/ In short words, you can use the GPIO of the Raspberry Pi Zero without installing an OS on it: you don't need an SD card nor a power supply. You only have to plug the USB cable between your PC and the RPi, and you can drive the GPIO pins directly from your laptop or desktop. Deepening a little, even if I'm not an expert of buildroot and so on, the RPi Zero perform the boot of a minimal system via the USB interface and it emulates an ethernet dongle. I would like to write how to use such handy functionality on Fedora (and it's nothing complicated: you only have to clone the GIT repos and build the gpioexpander and usbboot programs) because reading various posts around the web, it seems that this feature can be used only on the Raspberry Pi Desktop (aka Pixel) and Ubuntu distros, and this is a misleading impression: in fact we can use also our beloved Fedora workstation, even if there are not RPMs available. Ciao, A. _______________________________________________ Fedora Magazine mailing list -- magazine@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to magazine-leave@xxxxxxxxxxxxxxxxxxxxxxx
