Question

Hello,

I am a student apart of my universities rocket design team and was wondering if it would it be possible to get some advice for our pcb design? We have the RFD-900 which when powered on before getting the gps to lock, seems to stop the gps module from locking and wanted to know where the noise from the RFD was coupling on the board. We would also appreciate any general tips and advice for the design, maybe if a representative would be available for a call we would greatly appreciate getting expert advice. I have attached a github link to the current pull request where the design is occuring and have attached photos as well. Thank you to anyone who assists.

Hi,

If there is noise leakage from the RFD-900 it would be important to fix it first, maybe check the harmonics of the frequencies that are being leaked. It will tell you more about where it is coming from. In terms of the any tips for the module. I think if you follow the guidelines on the datasheet it will cover everything.
