This is a powerful expansion board that is compatible with four major controllers: Arduino, Raspberry Pi, STM32 and 51 controllers. Meeting your every need for a robotic car, it can ensure that the onboard module resources are not affected after switching any version of the controller, and the sensor interface is compatible.
Equipped with a wide range of sensor interfaces, such as ultrasonic obstacle avoidance, 2-channel infrared obstacle avoidance, 2-channel light-seeking, 4-channel tracking, RGB lights, color recognition, MPU6050 gyroscope and linear CCD camera. Compared to the traditional open IO port and DuPont line connection, we use a simple and easy to operate modular design and socket cable connection. It is easier and simpler to make the wiring not rough.
3 motor drive capabilities, including 4-channel DC motor interface, 6-channel servo interface and fire-extinguishing fan interface.
With 9.6V-13.5V wide voltage input, the voltage is lower than 9.6V, and the over-discharge protection circuit automatically cuts off the power to protect the battery. In addition, the board also has a 12.6V charging interface, 3.3V/5V voltage switching, reverse connection protection, voltage monitoring circuit, forced reset circuit, low voltage prompt and stalled restart circuit to provide a stable power supply system.
Support 6 kinds of communication methods: Bluetooth interface, WiFi module interface, 24L01 wireless interface, SPI communication interface, infrared receiving (integrated) and CH340 serial circuit (integrated)
Support 5 kinds of control methods: mobile APP, PC computer, PS2 controller, infrared remote control and gesture armband.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- STM32
- STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
