Hardware compatibility catalogue

No one can buy every board — this is a community catalogue. Ran it somewhere? Add a row by PR, or post in Discussions with the template below. This is also how the honest "Tested on" grows beyond what one maintainer can verify.

Legend: ✅ works · ⚠️ works with caveats · ❌ no · ❓ untested (expected, unverified)

Device Arch RAM Profile Status CAKE ceiling Notes Reporter
Raspberry Pi 2B armv7 1 GB legacy-sbc ⚠️ n/a (not inline) sinkhole/print/fw/time/monitor only; no onboard RTC → add DS3231 maintainer
dev/CI: WSL2 Debian x86-64 ✅ authoring idle Virgin baseline ~12 ms / <1 ms jitter / 0 % loss (2026-07-15); configs authored + shellcheck/sh -n clean here maintainer
Raspberry Pi 4 / 5 aarch64 2–8 GB modern ~600–900 Mbit expected to work; not yet tested
Intel N100 (2× i226-V) x86-64 8–16 GB modern ~1–2.5 Gbit intended inline shaper; not yet tested

Keep it honest — a ❓ that becomes a ⚠️ with a real caveat is worth more than an optimistic ✅.

Right-size to your line — 2.5GbE is NOT a requirement

2.5GbE (i226-V) is headroom for gigabit+ inline shaping, not a baseline. Match the box to your actual connection:

Your connection Inline shaping Sidecar (sinkhole/fw/time/monitor)
Gigabit+ cable/fibre N100 + 2.5GbE headroom any capable box, 1 NIC
Sub-gig ≤ ~500 Mbps 1GbE + modest CPU (a Pi 4 copes) any Pi/mini-PC, 1 NIC
VDSL ~40–80 Mbps onboard 1GbE is plenty a Pi 2B is fine
5G/4G home box, hotspot often can't do inline (won't bridge) → sidecar; the mobile radio is the bottleneck anyway 1 NIC, anything

Rule: NIC + CPU scale with line speed, not a fixed spec. Most people never need 2.5GbE or even a second NIC — the sidecar Core (single NIC) is the majority path and runs on almost anything. Inline shaping + 2.5GbE is the gigabit-enthusiast tier.
