Serial Wiring

In order to daisy chain one servo to the next (serial mode only), rollover serial cables are used. Although the wires are straight, one connector is rotated 180 degrees with respect to the other. 

 

Serial Pinout

SQUARE-Yellow.pngServo Rx: In serial mode, this pin should be connected to a 5V TTL serial pin. In RC mode, the pin should be connected to an 5V RC PWM pin 
SQUARE-Yellow.pngServo Vcc: Refer to the Voltage section of the LSS - Specifications page to understand which voltages are meant to be connected to this pin.
SQUARE-Yellow.pngGround (GND): This pin should be connected to both the communication sources' ground, as well as that of the power source (principle of "common ground").
SQUARE-Yellow.pngServo Tx: In serial mode, this pin sends the output from query commands. In RC mode, the cable does not need to be connected as there is no output. 

RC Pinout

SQUARE-Yellow.pngServo RC Signal: Please refer to the LSS - RC PWM for more information regarding the RC mode and signals.
SQUARE-Yellow.pngServo Vcc: Refer to the Voltage section of the LSS - Specifications page to understand which voltages are meant to be connected to this pin.
SQUARE-Yellow.pngGround (GND): This pin should be connected to both the communication sources' ground, as well as that of the power source (principle of "common ground").

Electronics

The electronics inside the servo include the following:

  • H-bridge motor controller
  • Microcontroller (Cortex M0)
  • Magnetic position sensor
  • Voltage sensor
  • Temperature sensor
  • Current sensor
