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.

For some reason I recall seeing a setup of using a daughter board to log GPS data to an SD card, was that ever discussed on this site? I know recently there is talk about ArduPilot Pro / 2.0 doing logging, but this was with the original sim hardware, plus a second, smaller board.

Not here. Right now we're doing datalogging on the ground with our groundstation (TBA) and Xbee. We might offer onboard datalogging with ArduPilot Pro, which will be built on the Arduino Mega platform.

Ah, maybe I was thinking of the Xbee afterall. If I am not mistaken, the Xbee works to just transmit all data that comes across it, correct? no interpreting or formatting.. kind of like a repeater. The reason I ask would be for situations where ground station monitoring is impractical. I was thinking something like this device that you could run the wires from the GPS to both the ArduPilot board and that logging board. Would that work in theory?

Yes, that's correct about Xbee. It sounds like that datalogging board could indeed work.

Is there some documentation that labels your daughtercard other than the board itself? Something like "this pin connects to the Tx pin on the GPS".

Hi Guys......:)
Is it possible to connect iPAQ GPS with ardupilot circuit or any type of GPS. Cuz I would like to use the ardupilot circuit for sailing boat application to control rudder i.e. to set the rudder in autopilot mode by using ardupilot.
I notice the ardupilot can only function by using GPS module like EM406 or 5HZ type..Please advise me if the ardupilot is capable to control it by using other type of GPS i.e. not a programmable GPS but with display unit like iPAQ or Raymarine GPS's or any other types of GPS by re-program the ardupilot cicuit to be suitable with new module of GPS...All the best..

what software do I need in order to view the Eagle files (schematic and PCB) ?
I can't seem to open the file .

wow did you re-open an old blog...

but here is the eagle software link
