-| Raspberry Pi Zero 2 W | Zero W also works. Zero 2 W is current and quad-core. Headers not needed if the LED line is soldered. |
+| Raspberry Pi Zero 2 W | VERIFIED: the plain Zero and Zero W work too. `build.sh` already emits `kernel.img` for them, and the gadget's string descriptors are present in it, so either is a drop-in if Zero 2 W supply is a problem. Chosen anyway as the current and most available part; the quad core is headroom this workload does not need. Note a plain Zero would permanently close the WiFi option in section 3a. Headers not needed if the LED line is soldered. |
 | microSD card | Circle boots from FAT32. Tiny card is fine. |
 | WS2812B strip, 144 LEDs/m, 2m | Need 176 LEDs = 1.222m. Buy 2m, cut to length. |
 | 5V PSU, 6A | See the power note in section 7 before assuming this is enough. |
