UBTECH ALPHA1S Digital Servo Built-in AVR Develop Board 6V-9V UBT12HB

UBTECH ALPHA1S Digital Servo Built-in AVR Develop Board 6V-9V UBT12HB

Product Description:
- It uses chip singlechip MEGA8A,is a kind of micro servo motor,precision decelerating motor,a built-in control board for receiving instructions and control reduction motor
- All copper gear,output shaft has two ball bearings.
- Serial bus servo is a complex semi duplex communication protocol,The servo of each machine has the only ID.The main control board can communicate with all servos with a signal cable.

FA AF 01 04 01 00 00 00 06 ED switch off led light
Write servo:FA AF id 01 angle ? ? ? SUM ED
Servo response:FA AF id AA ? ?real angle sum ED
Read data:FA AF id 02 00 00 00 00 SUM ED
Present experiment order (CD order is modification servo ID.)
Order can do experiments in 01..FF sequence.
Frame header:FA AF;frame ender:ED,SUM=ID+order+parameter,get the lowest 1 byte
Frame header (2 byte) ID(1 byte) order(1 byte) parameter (4 byte) SUM(1 byte)frame ender(1 byte)
Communicaton protocol format (length:10 byte)
Initialization,electricity is on.And then separate it and control single servo with computer TTL.
Connect computer TTL serial to the servo port.The computer (sscom32 serial software) can record it to the file when playing robot.
Protocol analysis method:(need robot)

Modify ID:FA AF ID CD 0 newid 0 0 SUM ED

Note:The servo is serial bus servo,not analog proportion servo.The connecting cables,rocker arms and screws are not included.
