Description
Compatible with four controllers
Abundant sensor interface with strong expansibility
Strong motor drive capability
Stable power supply system
Multiple communication modes with Bluetooth app provided
The Yahboom 4WD Expansion Board for Robot Car is a powerful expansion board that is compatible with four major controllers: Arduino, Raspberry Pi, STM32 and 51 controllers. It ensures that the onboard module resources are not affected when switching between different versions of the controller, and the sensor interface is compatible.
This board is 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. It uses a simple and easy to operate modular design and socket cable connection, which makes wiring easier and simpler than traditional open IO port and DuPont line connection.
It also has 3 motor drive capabilities, including 4 channel DC motor interface, 6 channel servo interface and fire extinguishing fan interface. Furthermore, it has a 9.6V 13.5V wide voltage input and the voltage is lower than 9.6V, the over discharge protection circuit will automatically cut off the power to protect the battery. Additionally, 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.
It supports 6 kinds of communication methods: Bluetooth interface, WiFi module interface, 24L01 wireless interface, SPI communication interface, infrared receiving (integrated) and CH340 serial circuit (integrated). It also supports 5 kinds of control methods: mobile APP, PC computer, PS2 controller, infrared remote control and gesture armband.
