![]() ![]() I replaced the Split+'s ribbon cable with a shorter one that also has a male 40 pin IDC header crimped to it so I can still plug in pHATs when breadboarding. Other hardware choices included a Cyntech Split+ to get the expansion header into the breadboard and a 16Gb Micro-SD card that had originally come with a PI 3 B with NOOBS on it, and a K&H AD-12 breadboard. The Bluetooth is both a blessing and a curse as it uses the BCM2835's main PL011 hardware UART and the auxiliary mini-UART that is normally routed to the TX and RX pins on the expansion header doesn't have a proper baud rate generator so its speed varies with the CPU clock, making it essentially unusable unless you either clock down the CPU and lock its speed, slugging performance, or disable the Bluetooth in config.txt so the main UART can be rerouted to the expansion header before the kernal loads. A plain Pi Zero wouldn't be able to access any network except through the host PC, so I bought a PI Zero W with onboard WiFi and Bluetooth. You cant use any PI with on-board Ethernet or multiple USB 'A' sockets, as the on-board USB hub /Ethernet controlled chip blocks device mode access to the BCM283x SoC's USB port. USB Gadget mode) has been available in the Rasbian kernel since mid 2016, a Pi Zero or Zero W (or Compute Module or even a model A) can be networked to a PC by USB, appearing as a RNDIS adaptor to the PC. As USB OTG support for the Pi Zero (a.k.a. Choice of hardware For breadboarding I wanted a cheap and simple hookup with the minimum number of cables. ![]() ![]() Due to the legacy windows OS, and my dislike of WiFi for home networks, I ran into various issues along the way. Rationale - Why headless? I don't have a fancy monitor with DVI or TV with HDMI and I wanted a low cost setup for experimenting with Pi interfacing so I decided to get a Raspberry Pi Zero W and run it headless from my Windows XP netbook. Some ramblings and jottings on my experiences with running a Pi headless, tethered to a Windows PC, and breadboarding with it. ![]()
