I AM DEVELOPING A CUSTOM BOARD USING NEO-N9N-00B.I CHECKED THE SCHEMATIC OF SPARKFUN GPS NEO-N9N UFL. I GOT CONFUSED ITS ANTENNA SCHEMATIC. ( CI160808-33NJ )THIS COMPONENT IS NOT FOUND IN IT. AND THE RESISTOR (R14) RANGE WAS NOT FOUND. CAN I GET THE CONFORMATION ABOUT IT.
The bead can be found at Digikey
The schematic shows the resistor as a 10 ohm part.
IS CI160808-33NJ OPTIONAL IN THIS SCHEMATIC?
CAN I GET THE BOM OF SPARKFUN GPS NEO-N9N UFL SCHEMATIC
Hi Rohith (@ROHITHINTHINGS ),
The inductor, resistor and capacitor not optional. They filter out noise from the 3.3V power supply and limit the current if the antenna cable develops a short circuit.
You can download the Eagle CAD files for the board. Eagle has a BOM tool which will show the part numbers.
10 Ohms is a safe choice for the current limit. If your active antenna needs more than 10-20mA, consider reducing it to 4.7 Ohms.
I hope this helps,
Paul
