Description:

The Dynamixel MX-28R TTL Serial Servo is the newest generation servo from Robotis. Equipped with an ARM Cortex M3 features a PID control algorithm and provides feedback information such as speed, temperature, position and load. Over a simple TTL Serial interface you can command, configure, and access information from several daisy-chained servos

Features and Specifications:

• Operating Voltage: 12V
• Communication Protocol: TTL Half Duplex Async Serial*
• No-Load Speed: 55 RPM
• Stall Torque: 25.5 kg-cm
• Resolution: 0.088 degrees
• Gear Ratio 193:1
• Maximum Current: 1.4A
• Standby Current: 100mA
• Dimensions: 35.6 x 50.6 x 35.5 mm
• Weight: 72g

NOTE: This one-wire TTL interface can not be directly used by an Arduino. You will need dedicated hardware to make the connection since the Transmit and Receive share the same serial line. The suggested solution is to use a Tri-State buffer (TE-234-241).
