Hi, I have assembled and successfully ground tested an Eggfinder Mini GPS with a 2S 200mAh lipo at over 300 M when the tx in my car.
However when I connect anything else to the Lipo - even just a single short wire to a Quark 0v terminal - the Mini seems to struggle to even transmit data across my workbench - the red led on the Tx is still flashing and the GPS lock led is lit but either no data received or the GPS repeatedly disconnects and reconnects every few seconds (as seen in the Rocket Finder app - Bluetooth option for the receiver). Remove the connection to the Quark and GPS data is clean and consistent.
I tried (as a test) to run the system from a 2200mAh 35C Lipo to see if the (small) battery was at fault - no improvement.
I have tried stranded and solid Cat5 cable pairs, short and long lengths for the wiring, - upto 125mm - no good.
I tried just one wire connected to the Quark cut off switch - the Mini still 'failed'.
I have had email conversation with Cris - he was helpful (as usual) but could only really advise shortest possible twisted pair leads from the battery to the Mini - it works perfectly with short leads / twisted pair direct to the battery but I was hoping to use a single battery to power the Mini and the Quark.
I think I may be missing something☹, I have run out of ideas, so I thought I'd ask the great pool of knowledge this forum has proven to be.
As there are many experienced Eggfinder product users out there I was hoping someone had the definitive answer - can you run a Mini GPS on a common battery with other components (eg Quark), if so does anyone have details, pictures, description etc of the configuration?
Of course it could be a bad assembly (self built) - but it works so well when its 'lonely'.
Ta,
