Listed speed is 400–2800 RPM, with stop below 3% PWM. The proposed 35% minimum control command stays above that threshold. The firmware’s two-pulses-per-revolution scaling remains an assumption to verify against an optical tachometer; this specification does not state pulse count.++<!-- aiflow:steps -->+## How this board was built++Every step of the build, in order, each with its own page of evidence (checks, screenshots, the AI's drawings and usage), written by [adom-aiflow](https://wiki.adom.inc/adom/adom-aiflow) as the run went.++**1.
