The new Lassen iQ FAT16 Datalogger board is possibly the coolest thing I’ve seen this week. Way to go Sparky! (oh, and you to, Pete).
Next Step: LoJack Lite!

Whoops! That was me (forgot to log in).
will it work with other nmea gps modules?
I have a lot of axiom sanpipers
I also would like to know if it works with other gps devices. Sparky, remember you made me a couple of boards for a U-Blox gps receiver, it would be great if I could connect my gps unit with this datalogger.

Yes…I owned a EM406, If this is workable, I thought I would buy one datalogger as well
OK, this is just a guess on my part, but I’m fairly sure. The module was designed to work with the iQ. Not only could there be other command sets for the other GPS boards, but they also use different power supplies and pinouts. So, barring extensive modification, this is limited to the iQ only (for now).
Although that does add another possibility. Change the board design to a mainboard and use a daughtercard to mount other small modules, or have a TTL or RS232 serial connection for others yet (UBLOX). This still might be an option with the current connector, although it’s not as easy to work with as standard 0.1" headers 
Sparky and crew would have to figure out a command TXT file format on the SD card to provide “startup configuration” AT commands to the ARM chip. That would allow configuration (if needed) of any AT serial command chip. I dunno how much more that would take, though.
Ugh - I’ve been bad at not checking the forum. Congrats kids, there are 6 new pages of posts. Way to keep the community alive and rocking!
The GPS logger was a fun project. Owen found the example LPC code for the FAT16 routines from a circuit cellar article. He then found and corrected about three bugs in their code. Owen and Pete now build all sorts of widgets using SD media. Next, Pete tried to sell me on a Lassen iQ logger. I told him I didn’t think it would sell well. I was wrong…
Currently the logger is only setup to read directly from the Lassen iQ connector. Obviously we didn’t have to forethought (sp?) to build in an external connector to allow you to log from any NMEA based GPS receiver. Thanks for the idea! We’ll try to build it into the next rev.
For now - you should be able to back-out the Lassen iQ TX pin position and connect any 3.3V TTL GPS receiver (ET-301, EM406 with a 10k resistor, etc) and have it record in basic NMEA log mode. The special XML mode probably will only work with the Lassen iQ for now.
Just a note - that really was Casey’s lunch and we didn’t touch-up the images or data. It really did fit that well. Scary.

Well done on dredging up a 2 year old thread…
