New ArduPilot Pro boards
The latest board, shown above, updates the previous board in a few ways,. We took the GPS module off the board to give you more flexibility over which GPS use and where it is. Instead, we use a EM406 connector, which you can either use for a 5v 1Hz EM406 or use our soon-to-come daughterboard (which also uses the EM406 connector) for 3.3v 5Hz modules.
As before, you need to buy a FMA IR sensor modules (here) or build ours.
You can buy the board here.
The Eagle files are here: Schematic, PCB.
Here are the components you'll need:
- (IC1) 2x Atmega168, ATMEGA168-20AI-ND
- 2x DIP sockets, 28-pin sockets
- (IC2, multiplexer) 1 x 74LS157D,296-14884-1-ND
- (IC3) 1 x ATTiny45, ATTINY45V-10SU-ND
LEDs:
- (D1-D4) 4x Navi LED (green) 67-1357-1-ND
- (D5-D8) 4x Navi LED (red) 67-1357-1-ND
Capacitors:
- (C1, C3-12):11x .0uF capacitor: PCC1828CT-ND
- (C2):1x 10uf capacitor: sparkfun
Crystal:
- (X1, X2) 2x 16MHZ SparkFun
Resistors:
- (R1,R4, R13) 2x 10kOhms P10.0KCCT-ND
- (R2, R3, R5, R6, R8, R9-12) 10x 1Kohms P1.00KCCT-ND
- (Trim pot, not marked on board but the three holes in a triangle next the "pot" lable): Trimpot 10k
Connectors:
- 1x 3-pin Thermopile connector: polarized connector
- 1x 4-pin Thermopile connector: polarized connector
- GPS connector: EM-406 connector
- 3x Header strips: breakaway connectors
Switch:
- (S1) 2 x Switch SMD, sparkfun

the Thermopile connector is not the same as the infrared module, they need to make an adapator... Until we find the correct library with the tiny connectors...

the plans of sell it with custom IR sensor and GPS for 100$ or less, are still "up" ? or finally will be sold just the board?

We have not yet decided what form we'll sell this in. We may just sell the board and GPS and recommend that you use the FMA sensor heads.

it dont worth in price and weight sell the custom sensors than buy the fma head?

Can I ask what the line of thinking is regarding discontinuing with the open source thermopile heads Chris ?
-

@Marty: FMA has a patent on those sensors. If you make them yourself, no problem, but if we make them, we may have to pay FMA $7 per set, a few thousand dollars upfront, and they may attempt to set our pricing. Ugh.
But to be clear, if you want to make your own with our board and sourcing the parts yourself, that's fine.

I thought that may be the case Chris, especially after all the hoops Dean has gone through. Would there be any restrictions on you providing an alternative design and cheaper thermopiles like you do now ? Is the restriction more related to producing and selling complete boards ?

The patent covers using thermopiles to control aircraft. It's pretty general. But if people want to solder their own, that's fine. I just don't want to be in the business of selling bare thermopiles. I made one bulk purchase, but won't be making another.

You (and the link) call for the Attny 45 but the silkscreen calls for the Attiny 12p and is a different package (DIP?) than the attiny 45 (SOIC?). Any clarification on this? Thanks,

This is an ancient version of the board. We've now switched to the Attiny45 (soic), and the code is now designed for that.
