Atmega8 Digital Servo Control Shield

SKU: DRI0027

The Atmega8 Digital Servo Control Shield integrates a half duplex circuit enabling communication with over 200 AX-12 servos through a serial bus, providing feedback on each unit's position, rotation velocity, torque, and more, making it highly suitable for wheeled and tracked robot applications.

    More Details

    • POWER SUPPLY: 6.5~12V power supply for servos & the whole system.
    • UART SELECT: UART is already shorted by solder. When you use the UART FOR ATmega8 please remove solder off.
    • UART FOR ATmega8: This UART interface is for deeper development of the shield.You can program the atmega8 on the board with FTDI.Board choose "Arduino Optiboot8 "
    • SS SELECT FOR SPI: Digital pin 10 in default.If you want to use other digital pins,please remove the jumper cap and connect the ss header to other Arduino digital pin.

    FAQ

    • HI, i recently bought one of these Shield, to run an AX12_A Dynamixel servo... i hooked it up to an 11.1 voltage source, with one servo connected and uploaded both libraries....but when i attempted to run the example code nothing happened....has anyone else had this problem and can suggest a solution to make this shield operational ?

      Hi Kerwin, sorry for the missing information. As a early product, the shield was designed and developed to servo control, and it doesn't integrate information feedback system. It means you could control the servo, just without feedback. That is more convenient for the guy who is new to digital servo.
