Fourth, a better datasheet would provide for three essential use cases: open-loop speed control, direction reversal with braking, and basic encoder feedback (if the shield breaks out encoder pins, which many HW-130 variants do not — but a better datasheet would honestly state that limitation). Crucially, each code example would include comments explaining why certain pins are set as outputs and how to avoid shoot-through conditions. hw 130 motor control shield for arduino datasheet better
