I use Openmv4 with TOF module on the unmanned aerial vehicle,but openmv sometimes shut down. The main.py works fine when not on the fly.
So I suspect that the Power is limitted when on the UAV.
I wonder How much current i need supply to make it work well with TOF(U=4.5V to 5V).
The China Store says about 200mA to 500mA.I am not very sure

Um, the OpenMV Cam needs about 200 mA. How is the system and the ToF unit powered? You could use a second battery which may ease the problem.

Hi, just post on https://forum.singtown.com/category/5/openmv-cam

Please paste all codes, and I will test.
You could also contact customer service on taobao.

By the way, the distance shield is so low-power, it is under 20ma.

If you buy a genuine board, you will certainly get a genuine service, and vice versa.

If it is genuine, just contact the seller, the problem can be solved directly. It is impossible to run an error in the example.
