GPIO and I2c both work properly; my code uses both. Just be aware that if you're doing anything I/O or seriously compute-intensive that the CPU and I/O arrangement on these boards is less-than-optimal.=C2=A0 In addition the lack of instruction-set crypto m= eans you can run into bottlenecks there if you're doing anything that requires cryptography, although for reasonable-performance stuff, which I do rely on heavily, it's fine. I build my own codebase using Crochet on my main systems; one of the other "gotchas" with the PIs isn't really a Pi thing at all -- it's that SD cards are designed for moderate volume of large writes (think photographs, music files and videos) which is wildly different than than the workload they see running as a general-purpose Unix box.=C2=A0 They a= re very slow in small-write, many-write use and over time can get unstable; when they fail their usual failure mode is to permanently write-lock themselves which results in an instant panic and typically a failure to reboot since the filesystem is corrupted by the event.=C2=A0 In an embedd= ed application this is unacceptable and is one of the reasons to build using Crochet since it runs R/O once operating with /etc and /var contained in a ramdisk. IMHO if you're thinking more of a "firewall or edge" appliance the Pi4 (once we have working code for it) may be a materially better choice but, if you need it now, I'd give serious consideration to the pcEngines SBCs.=C2=A0 I have a bunch of those in the field in that application and they've proven superb over time -- they too can boot of SD card but also have a mSATA port internally which means they can use a M2 SSD which is a LOT faster and more-stable than using SD media.=C2=A0 In addition they = have multiple gigabit interfaces and have no hardware infirmities in being able to actually drive them at wire speed, plus having AESNI instructions if you are using them as a VPN gateway they are a LOT faster than the Pi units are in such an application.=C2=A0 I use NanoBSD = for those too and boot from the (full-size) SD slot simply to make them "power fail safe" on restart. To get it running and start working with it the snapshots or RELEASE codebase is fine. --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email
