USB port communication, computer control
1. When remaking a PC cooling fan, cooling water pump, etc, you can manually control the device on PC, or make it be automatically adjusted by reading the CPU temperature.
2. Because the host computer can accurately adjust the frequency and duty ratio, this driver can be used to test dc motor or light strip products, or to optimize small equipment.
3. Make a small fan whose wind speed can be automatically adjusted or controlled on the computer. Just plug in the USB to use.
4. MODBUS communication protocol.

UART communication, programming control
1. Create a project with special effects, or turn it on at a specific time, or adjust lighting effects, or use it with sensors. For example, a fan that automatically adjusts the wind force, and a light strip that automatically changes its brightness.
2. Automatic control of the water output of the fish tank or watering pump.
3. Automatic control of festival atmosphere lights.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- Modbus
- Modbus is an industrial communication protocol used by many meters, sensors, PLCs, and automation devices. Modbus support matters because it can make the controller easier to integrate with existing industrial equipment.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
