Subject: Technical Inquiry - Power Specifications for RealSense D435i and D457

Dear Intel RealSense Support Team,

I am writing to request detailed technical specifications regarding power consumption and power supply requirements for the following RealSense depth camera models:

  • Intel® RealSense™ Depth Camera D435i

  • Intel® RealSense™ Depth Camera D457

Specifically, I need the following information for both models:

  1. Power Consumption (Watts)

    • Typical power consumption during operation

    • Maximum power consumption

  2. Current Consumption (Amperes)

    • Typical current draw

    • Peak current draw

  3. Supply Voltage Requirements

    • Operating voltage range (minimum, nominal, maximum)

    • Voltage tolerance specifications

  4. Power Supply Interface

    • For D435i: Confirmation that USB Type-C interface provides both data communication and power supply

    • For D457: Confirmation of GMSL/FAKRA power supply method and specifications

  5. Power Budget Recommendations

    • Recommended power supply capacity for stable operation

I have reviewed the product datasheets available on your website, but I could not find complete power consumption specifications for these models. This information is critical for our system integration and power supply design.

Could you please provide detailed documentation or technical specifications addressing these power-related parameters?

Thank you for your assistance.

Best regards,

    Thanks very much for your questions!

     

    D457 power consumption in mW can be found on page 47 of the D457 data sheet.

     

     

    Regarding D435i, the power consumption of its Vision Processor D4 V3 board can be found on page 103 of the 400 Series data sheet.

     

     

    The diagram below on the same page describes the power requirements of the overall camera (the D4 V3 board and the D430 module together).

     

     

    2.  Page 35 of the 400 Series data sheet describes the D4 V3 board's power requirements in amps.

     

     

    Page 25 of the D457 data sheet provides the D4 V5 board's power requirements in volts and mA in USB and FAKRA modes.

     

     

    It is recommendable that a maximum of 2W is budgeted for each camera.

     

    I confirm that on D435i, USB provides both power and communication.  On D457, power and communication is through the FAKRA cable, unless the hidden mode switch under the removable cap on top of the camera has been moved sideways to put the camera into USB mode instead of FAKRA.
