power monitoring on Firefly-RK3288 Reload

solidrepellent

Hello,

I would like to purchase Firefly-RK3288 Reload so that I can monitor individual power rails (CPU, GPU and if possible RAM) and check the power consumption of my algorithm using external measuring equipment.

Is it easy to monitor power with external power measuring equipment? I need easy access to power rails. I have some soldering knowledge and know people who can mod the system if required. Please let me know.

Thank you for your time.

Hi
yes ,you can monitor these individual power rails.
the CPU and GPU power supply separately.
for instance, monitor the CPU power ,connect your equipment to L26 (the inductor in the following picture).





and the  GPU power is similar.

Thanks everyone for sharing detailed information about power monitoring on Firefly-RK3288. I find this process of measuring and optimizing power is similar to playing solitaire bliss, need to calculate each step, monitor each power line to achieve optimal results.

Thanks for all the details about power monitoring on Firefly-RK3288! When I need to quickly add up measurements or results, I usually use a sum calculator online — super handy for engineers!
