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!

I tried to look in the eagle files, but i couldn't solve the puzzle. How many of the servo inputs are routed to the Mega168 or the ATtiny? And how many outputs from the Mega is routed to the Mux?

Are the eagle schematic and layout files available for the shield board? I wanted to get the footprint for the MPXV5004DP differential pressure sensor.

Hi Chris,

For the ardupilot with Atmega 328 is the same components list os Atmega 168?

Regards.
