"In order to use the 3.3v ext compass on pixhawk and avoid the 3.3v to 5v problem, connect the VCC wire to the second pin (from left to right) on SPI port, as it is 3.3v, and leave the other 3 wires on the I2c port as you would normally."
"I managed to solve this by connecting the VCC wire not to I2c port but to second pin (from left to right) of SPI port, as it reads 3.3v on my multimeter. Works ok, no problems so far."
Dear modelers, I need an older version of Arduplane hex to upload do my board: up to 3.2.3, as newer versions don't have the camera mount code for APM 2.5, but can't find it on mission planner or at http://firmware.ardupilot.org/ , only newer…
Dear sirs,I'd appreciate your help. My knowledge in electronics is not zero, but very limited.I have an APM2.5, with Power Module, GPS, external compass and 3dr-like telemetry V1, on a plane, a big 2.2m span weasel-like flying wing, twin-motor,…
I live in Brazil, and I am developing a drone for precision agriculture. I'd like to know more about your dual-camera setup. How do you merge both pictures?
I was wondering: as the pitot tube is an air inlet, what would happen if, during flight, the plane caught some rain, or flew through a low clowd? The plane can be made water resistant, but what if the water enters the pitot tube and goes to the…
If you really want to discuss efficiency, tailed designs are better. They need less wing area to carry the same weight, and you have an excelent performance with flaps, for short, easier and safer landing and takeoff. Less wing area…"
