Buy bare boards and components for a DIY ArduPilot

You'll soon be able to buy ArduPilot already made, but for those of you who would rather build their own, here are the necessary parts:

You can buy the boards here.

Eagle (PCB and schematic) files are here.

A pdf of the schematic is here.

Once you've made the board, instructions on setting the fuses and loading the bootloader are here.

A few notes on building the board: Aside from all the surface-mount components below, the only through-hole components you need to solder on are a 5-pin breakaway connector for the FTDI port (first five pins next to the GPS connector), the two 2x3 ICSP connectors, two 3-pin connectors for channel 1 & 2 output, one 3-pin connector for the power select and three pigtails (female-to-female servo connectors cut in half) for CTRL and channel 1 & 2 in. The other two channels (3&4) are not currently used. IMPORTANT: the power selector pins must have a jumper cap placed on two of the pins. Use the two closest to the servo-out ports if you're going to power the board from the RC receiver via the RC-in cables (that's what I've done in the picture above), or use the other two if you want to power the board with a separate regulated 5v power source. If you don't put the jumper cap on these pins, the board will have no power!

ardupilot needs the fma copilot as well, right?

Yes, and you need a plane, too ;-) I'll update the post (which was really just about the board) to include others things that people may not have thought about.

Will EM411 GPS work instead of EM406?

We've never seen an EM411 (actually I've never heard of it), so I don't know. If it uses the same connector as the EM406 and spits out standard 9600 NMEA it should be okay.

Hi Chris,

Any idea when they will be ready for sale? Also, will shipping to Australia be available?

How about using this GPS: ?
Is uses the same chip as the LS20031and at the moment it can be bought for $57.95 (a modest $2 saving) The possible advantage of this is it has a SAW filter.
Also, for those of you are into fpv and have an OSD (Eg Dragon, blackstork IFOSD), you will likely already have this GPS.

Oops, here is the link.

I've got one of those. Unfortunately, the ceramic antenna is too small and it's not as good at picking up sats as its big brother. For OSD it may be good enough, but we need greater reliability for autopilots.

Ah, Ok.
Chris, i know you are constantly asked this, but are talks going with your manufacturer?
Are you any closer on an ETA for the ardupilot?

Same answer as always: before the end of the year, I hope.
