I'm trying to create a very simple module that consist in powering a GPS ublox - NEO-M8U - with a micro USB & using an active antenna.
Later on, I will add more features but I just want to make sure I'm doing things the right way by keeping the noise at the lowest.
Here's what I did using information I found mainly on stackexchange.
I decided to go only with a 10uf capacitor for the Vin. Some people are in using 22uf, 100nf & 10uf in parallel. Would that make sense to use more capacitors on this side on the circuit ?
For the GPS, I went with this :
I'm just not sure about the inductor. The problem I have is that I want my card to be directly assembled by the PCB supplier and they did not have the 27nh recommanded by the GPS manufacturer. Also I really don't know how to choose such inductor. Do people have good practices for that ?
My last question is for the board design. Should I have the biggest capacitor the closest to Vin ?
