Unit v2 / Unit v2 m12 power consumption

[mshepard67]

Hi there,

Looking for info on average power consumption for M5Stack Unit v2 and Unit v2 M12 cameras. Application is object detection, with posting image + data periodically over WiFi when we see something of interest. Trying to spec power requirements for solar powered implementation.

Thanks!
Mark

What is on the M5Stack website?

@ajb2k3 The M5Stack website just lists input power (5V @ 500mA). What I need is actual power consumption for the device. Ideally to know what it actually draws during normal operation, when modem is used, sleep modes, etc.

@mshepard67 Well, it draws a lot of power , so I don't think solar is a good power source. They run Linux and power an TF card!
These are AI cameras and the 'teaching' period is very long and difficult.
What is your end-use, if I may ask?

@teastain - thanks! The end-use is a bird feeder that classifies the birds it sees. Something like this: https://www.birdfy.com/products/birdfy-feeder

Not planning on training a model for the UnitV2 - the out of the box Yolo and Nanodet models recognize "bird" as a class. Idea is to capture an image when it sees bird and then send it to a server via wifi for species-level identification using a finer-grained classifier. Will put the unit to sleep at night.

Thanks for pointing me to the overheating issue. That may sink the selection of these cameras for this use.
