Hardware version
CANBench Duo v1.1 — Fabricated prototype, sole built unit. V1.1 is electrically identical to the V1.2 schematic refresh but predates the InvenTree symbol-library migration; the schematic component metadata reflects legacy SCADYS naming. Testing and bench validation reference this V1.1 hardware.
Other versions: v1.2 — schematic refresh (next version)
The CANBench Duo V1.1 BOM, grouped by Value. Sources are sample suppliers; substitute equivalents permitted where noted in Circuit Design.

The Datasheet column carries manufacturer URLs where reachable. Several parts (the LED, the TPAZ1023 TVS, the muRata MLCC family, the PROD Tech inductor, the Changzhou Amass bananas, the HCTL SMA, the Shenzhen STA M12, the Shouhan CYA0630) do not have publicly indexed English manufacturer pages; refer to the canonical LCSC redirect URLs in the engineering BOM (
PCB/CANBench_Duo_V1.1/schema_review/) for those parts.
