UNIHIKER M10 Dual DC Motor Driver Expansion Board

SKU: DFR1136

This product is a carrier specifically developed for the UNIHIKER. It uses a tilted edge connector slot to provide the screen with the best viewing angle. It integrates dual DC motor drive, which can be powered separately. At the same time, the board carries RGB lights, infrared transmission, infrared reception functions, and extends 10* 3Pin ports and 4* I2C ports. In combination with DFRobot's powerful Gravity product system, the UNIHIKER can create unlimited possibilities.

    Pinout

    No. Feature Description
    1 IR TX Infrared transmission feature, controlled in the same way as regular infrared transmission modules.
    2 IR RX Infrared reception feature, controlled in the same way as regular infrared reception modules.
    3 RGB LED The on-board RGB light is a series of three WS2812 lights, controlled in the same way as regular WS2812 lights.
    4 Edge Connector Insert the edge connector of the unihiker m10 into this interface, with the screen of the unihiker facing upwards.
    6&13 Motor Interface Each motor is controlled by two signal lines, one signal port outputs high and low level to control the direction of the motor, and the other signal port outputs PWM to control the motor speed. P5 controls the direction of M1, P8 controls the speed of M1, P6 controls the direction of M2, and P16 controls the speed of M2.
    5&14 Motor Signal Indicator Light The on/off state indicates the forward and reverse signal status of the motor, and the light brightness can indicate the control signal PWM speed status.
    7 VM Indicator Light Indicates the power status of the motor, the motor power is only provided directly by the Power In interface.
    11 I/O pin A module for connecting various 3-pin 2.54mm pitch Dupont female connectors.
    12 I2C Four I2C interfaces, one of which has a voltage of 5V, used to power high-power devices like Huskylens. Note that this interface can only provide 5V voltage when the VIN port or the expansion board Type-C port is powered separately. If the expansion board is not powered separately but is powered from the Unihiker, this interface cannot be used normally.
    15 USB Adapter Interface Through the matching HY2.0 to USB adapter cable, the power and USB signals on the expansion board can be transferred to the Type-C port of the Unihiker, enabling both the Unihiker and the expansion board to be powered and communicated with by plugging in only one power source.
    8&9&10 Power Supply Method Explanation
    1-From the Unihiker Type-C interface: Plug into the computer USB port, suitable for daily programming and debugging use, the motor and 5V I2C on the expansion board cannot be used, other functions can be used normally.
    2-From the expansion board Type-C interface: Input 5V power supply, suitable for daily programming and debugging use, the motor on the expansion board cannot be used, other functions can be used normally.
    3-From the expansion board DC2.1 interface: Input 6-12V power supply, can supply power to all modules on the expansion board. The matching DC2.1 adapter can be used to convert the DC head to a wire column. The matching USB adapter cable can transfer the power on the expansion board to the Unihiker.

    When unplugging the USB adapter cable, make sure to press down the buckle first, then unplug the cable. Do not use brute force to pull the interface.
