The Fix : Isolate the board by unplugging the and A- wires. Replace the fuse and power the board on. If the fuse survives, check your motor coils for grounding faults. If it blows with the motor isolated, the board's bridge components must be renewed. Motor Stutters or Jerks Irregularly :

: Connected via designated control terminals ( I1 and I2 ). Shorting these inputs safely drops the armature output voltage directly to zero without opening the primary AC mains line, enabling quick emergency stops and safety switch integrations. Full Terminal Wiring Map jymc220bi schematic full

| Feature | Benefit | |--------|----------| | 4.5 V – 38 V | Works with a wide variety of battery packs and wall‑adapter voltages. | | Fixed output: 5 V (1 A) or 12 V (0.5 A) depending on the variant | No external feedback network needed for the most common voltages. | | Integrated MOSFET + inductor | Minimal external parts → tiny PCB footprint (≈ 15 mm × 10 mm). | | Built‑in protection: over‑current, over‑temperature, under‑voltage lockout (UVLO) | Safer for both the module and the load. | | Low cost & high availability | Ideal for budget‑sensitive projects. | If it blows with the motor isolated, the
