Powering Pivistation 5 AI Kit (Hailo) from a 3S LiPo for a mobile robot

  1. Where did you get the camera module(s)?
    Purchased as part of a complete Pivistation 5 AI Kit.

  2. Model number of the product(s)?
    Pivistation 5 AI Kit — Hailo variant (64MP Hawkeye autofocus camera + Hailo-8L M.2 module, official Raspberry Pi case).

  3. What hardware/platform were you working on?
    Raspberry Pi 5 (as shipped in the kit), running the pre-installed SD card image. I’m building a small mobile robot and the kit will be the main compute unit.

  4. Instructions you have followed.
    The Pivistation 5 quick start guide in the Arducam wiki. The kit works fine on the official USB-C adapter — my question is about powering it from a battery instead.

  5. Problems you were having?
    Not a fault — I need guidance before I connect battery power, so I don’t damage the unit.

My power setup:

  • Battery: 3S LiPo, 11.1V nominal
  • Regulator: 8A UBEC, output set to 5.0V
  • The same battery separately drives two 12V gear motors

On my unit, GPIO pin 4 (5V) and pin 6 (GND) already have wires attached that appear to feed the Hailo board. Pin 2 is free.

  1. What help do you need?

a) What is the recommended way to power this kit from a DC source instead of a USB-C PD adapter — through the USB-C connector, or by injecting regulated 5V into the GPIO header?

b) If GPIO injection is acceptable, is it safe to feed 5V into pin 2 alone, given that pin 4 already carries current to the Hailo board? Roughly how much current does the Hailo board draw through those wires?

c) What is the actual peak current draw of the complete kit (Pi 5 + 64MP camera + Hailo) during boot and during sustained inference? I’ve seen 7.5W quoted, but I need the peak figure to size my supply.

d) If I power it through a USB-C breakout with 10k pull-up resistors on CC1 and CC2 (declaring 3A), will it run reliably, or is usb_max_current_enable=1 required in config.txt?

e) Any recommendations for avoiding brownouts when the motors start? I’m concerned about SD card corruption.
