Re: Low cost GPS receiver?

Chris, one side of the level shifter is 3.3V, the other is 15V.  If I am powering it by the VCC at 3.3 or 5V, how does this work? 

There is obviously a simple answer, but I cannot formulate the Google query.

Pretty much any of the GPS receivers we mentioned would work on a raspberry pi plugged in with dupont jumpers.

You can get level shifters with DB9 connectors for about the same price as a GPS module.

This one even has pins and dupont jumpers

And then you power the gps receiver over usb but ignore the native ublox serial port.

Gary, once an year, I ask for this, often on this list.

The "problem" I see with most modules like these is the UART voltage.  (Nearly) all are designed for Aurdino, so they work on 3.3V (TTL?) logic.  I think HAL would like to plug this into an RS-232 port in a "server", so he needs the +12/-12V signals.

I don't see those products under $200 :-(

Ebay has many under $10:

Try to avoid anything older than u-blox 8.

GDB has a 'break' feature; why doesn't it have 'fix' too?
