This tracking module uses four tracking probes and optimizes the spacing layout. The two inner probes can precisely identify the black lines, while the two outer probes can assist the inner probes in identifying the black lines and provide warnings. The vehicle can recognize 90-degree turns and other complex road surfaces.
The knob-type adjustable resistor is combined with a professional operational amplifier circuit, allowing the adjustment of sensor sensitivity.
You can connect it to the intelligent car or expansion board using jumper wires or DuPont cables for various experiments. The module is reserved with holes for installing copper columns and screws, making it convenient for you to expand by yourself.
High-quality infrared probes, with onboard four-channel comparator circuits.
1.6-inch thick shock-resistant PCB.
The module uses 6-pin pins and has an anti-reverse connection design for interfaces, which can effectively prevent positive and negative pole reverse connection and avoid module damage. It is simple and convenient to use.
High-precision knob adjustment with a wide linear adjustable range.
Reference materials, driver source code and graphical programming tools are provided.
This cute silicone case is suitable for Micro:bit V1 and V2 development boards. All the openings are specially designed for the second-generation Micro:bit development board and will not affect the speaker, touch logo and microphone.
The dot matrix light is clearly visible: The thickness of the silicone shell is 1.5mm, the thickness of the dot matrix area is 1mm, and the thickness of the LED cell is 0.5mm. The dot matrix light can easily pass through the silicone shell and be clearly displayed on the shell.
The silicone shell has speaker holes, reset button caps, micro USB interfaces and battery power interfaces, which are convenient for sound playback, reset, power supply and programming of the development board.
Users can install it on expansion boards or robots. It not only protects the Micro:bit development board but also makes your work more attractive.
