Hello, im in a quandcopter project for a while now and I just figured out that I needed a current sensor on each Bldc Motor and one on the Geneal Battery Rail.
I wanted to go with a certain ACS712 "Fully Integrated, Hall Effect-Based Linear Current Sensor" but for that I need 5 ADC on my Microcontroller (ATSAM3X8E).
And, since I have 16 of them, thats ok !
But .... I dont know if I would use them :
- I need a really precise data that I can look into later
- I dont want noisy readouts ( 4x4A BLDCs + Buck converters + radio traciver ...)
should I use one ADC per Sensor, use the builts-in ADCs : that's enought, or dou you have any sugestions ?!
Thank you in advance
ok ... after checking the price, I dont know if thats really the component tha I need, if you know a cheaper one, that would be great !
