Requires no complex configuration with simple wiring, enabling rapid integration into DIY projects like handheld fans and mini coolersProduct SpecificationsInput Voltage: 3-5V (3.7-4.2V recommended for this motor and fan blade)Output Current: Approx. 3A maxMax Power: 15WIncludes battery charge/discharge protection; Type-C charging port supports 3W chargingBattery terminals: 2.0 reverse terminals (note polarity)Motor terminals: 1.25 terminalsIndicator lights: Red for charging, blue for full charge, green for operation, flashing when lowSpeed control: Six speed settings, seventh setting pauses; long press also pausesBattery charge/discharge protectionLow voltage protection at 2.8VLocked rotor protectionNo-load protectionOverload protectionSupports 1S batteries (3.7V-4.2V)Compatible with 1103, 1104, 1106, 1306, 1407, 1503, 2418 brushless motorsImportant Notes1. When disconnecting the 2.0 reverse terminals from battery terminals, do not forcefully pull—use proper technique.2. If polarity is incorrect, use tweezers to swap the positive and negative wires.3. To reverse the positive terminal, remove the female terminal from the PCB and reinsert it upside down.4. For three-phase motors, all three wires are positive. Swapping any two wires reverses rotation direction.Package Contents:Module12.0MM 2P Terminal Wire11.25MM 3P Terminal Wire*1
