Castle Serial Link

Product #: 010-0121-00

UPC code:819326010569

The Serial Link device will allow you to communicate with Castle ESCs through the Castle Link Live protocol. This allows access to real time telemetry feedback from the ESC.

The device is capable of communicating through several serial protocols (e.g. TTL Serial, I2C, SPI). The serial protocols allow you to control the connected ESC's throttle level in real time while reading current operating conditions such as battery voltage and motor RPM. The device also has the ability to be controlled through an analog input, or can be used in a pass-through mode. The pass-through modes allow the Serial Link to receive the throttle signal from either an Analog or PPM input, and still allow an TTL Serial or I2C connection to pull real time data from the ESC.

        • Lower Half (0V to 5V -> 1.0ms to 1.5ms throttle)
        • Upper Half (0V to 5V -> 1.5ms to 2.0ms throttle)
        • Lower Half Inverted (0V to 5V -> 1.5ms to 1.0ms throttle)
        • Upper Half Inverted (0V to 5V -> 2.0ms to 1.5ms throttle)
  • Combination Input Modes
    • TTL Serial (with Analog Input)
      • TTL Serial for real time telemetry feedback
      • Analog for throttle control
    • I2C (with Analog input)
      • I2C for real time telemetry feedback
      • Analog for throttle control
    • TTL Serial (with PPM Input)
      • TTL Serial for real time telemetry feedback
      • PPM for throttle control
    • I2C (with PPM Input)
      • I2C for real time telemetry feedback
      • PPM for throttle control

The pass-through modes allow the user to control the throttle level using a receiver or manual control using a potentiometer. These modes will allow the user to read the real time telemetry feedback from the ESC if Link Live mode is enabled. 

Example Applications

  • Computer control with telemetry feedback of a Castle ESC
  • Embedded control with telemetry feedback of a Castle ESC
  • Wireless* control with telemetry feedback of a Castle ESC
  • Analog control of a Castle ESC
  • Pass through operation to an external data logging device

*External wireless module required.
