I have a Pi HQ camera attached to my Pi 5 via an Arducam CSI to HDMI Cable Extension Module, it works perfectly.
I’m now trying to use a servo to focus the CS mount lens on my HQ camera.
I’m using an ESP32 dev board to do this and, ideally, want the dev board placed next to my Pi 5.
I’m hoping to use the CSI to HDMI module’s A, B and C pins to connect a dev board GPIO pin to the servo (attached to HQ camera) over my HDMI cable, and assume this will work as expected.
But I’d also like to power the servo via one of the A, B or C pins.
My question is: can the Extension Module and HDMI cable handle the current that my servo will use?
The servo is a standard SG90 type of servo, I found a thread on the arduino forum that states an SG90 requires up to 550mA.
In my use case the servo will be idle 90% of the time - maybe more than that.
It won’t be under any constant heavy usage.
Thx.
