Power Rating of StereoPi

Post by HASSAN MEHMOOD »

Greetings,
What should be the input voltage and current rating of StereoPi so that every component(2 camera, mouse, keyboard, Compute Module) will work properly?

You can consider StereoPi as a regular Raspberry Pi 3B+ for power consumption.
Here is official Raspberry Pi power notice.
For RPi 3B+ it is recommended to use 5V power adapter, able to provide up to 2.5A

Some facts:
1. In most of our experiments StereoPi + Compute Module + two cameras + WiFi dongle (not high power) consumption within 1-1.5A.
2. In our code we did not use full power of GPU. So if you use a very specific code to provide 100% load for ARM kernels, GPU, USB and Ethernet, you can theoretically need ~2.5A

I'd recommend you to use 2.0A and more power source, and your StereoPi will be happy.

Thank you so much Sir
The issue has been resolved, it was a power issue.
