I saw on the Linus page that he stopped selling the BBBmini kit, so I ordered a shenzhen2u, it arrived in 30 to 40 days.
In the kit, it features a mounting bracket for the HC-SR04, my question is: should it be mounted in front of the drone, to avoid obstacles / collisions? Or should it be mounted below the drone for the altitude hold function? Or can I put 2 sensors: one to avoid frontal collision and another to hold altitude?
I found in Banggood a breakout board with the I2C and UART outputs:
Could it be used?
I also read about the US-100, which seems to me to be more accurate. Can you tell me if I can like it?
Well, there are still many doubts ...
Thank you for your attention.
