New board to allow use of 5Hz GPS modules with ArduPilot

(Shown at left above, with a Locosys LS20033 GPS module for size comparison)

ArduPilot is designed to use the solid and reliable EM406 GPS module, which is a 5v, 1Hz device that works well under most conditions. But if you want more precise navigation, you may want to upgrade to the 5Hz Locosys module that Dean Goedde is using with AttoPilot. That's a 3.3v module, so you can't just plug it into the ArduPilot board. Instead, Jordi has designed a special daughterboard that does the following:

--Converts ArduPilot's 5v power to 3.3v power
--Provides a EM406 connector, so it's a direct plug-in replacement for the EM406
--Provides a break-out connector so you can add a wireless modem, such as a Zigbee.
--Power LED


We may release this as a pre-made product, but in the meantime you can make your own.

@Reto. Yes, any 3.3v power source is fine. It's best if it can share a ground with ArduPilot, however.

Anybody know what the typical turn-around on these boards from BatchPCB is? I ordered over a week ago, but the status is still "processing".

It's about 20 days on average

what about just using the sparkfun level converter board? Its just 2usd...

@Chris. You said it's better to share a GND of the LS20031 with ArduPilot. Could I power the GPS through any one of the GPS GND connection (with VCC 3.3V of course) and link the other GPS GND connection to ArduPilot GPS GND ? Would this suffice? thanks for your help.
By the way, my LS20031 and FTDI Basic Breackout boards arrived in today. The GPS is giving me my "plane" position on Google Earth! It flies although its speed is zero, without crashing... Isn't that great?

I forgot to mention the GPS signal is through a window (2 m from it). It explains the spread of positions.

Yes, as long as all the grounds are connected somehow, that should be fine.

Chris, I'm not sure if you were answering this question before but would this board work?

Nick, no, I don't think so. It's just logic, not power.

Ah, ok. Thanks
