- All four RC-in channels (plus the autopilot on/off channel) can now be read by the CPU. This allows the autopilot to read the initial throttle and rudder position when you switch to autonomous mode, so it can maintain speed and heading. The other two channels can be used for whatever you want, such as triggering a camera sequence or dropping an object. (Remember that the aileron and elevator channels are seperately controlled by the FMA Co-Pilot)
- There are now status LEDs for the failsafe (on/off) and the GPS (satellite lock).
- There is now a trim pot on the board so you can adjust the autopilot on/off position to suit your particular RC system.

raptor: this is a three-year-old post about a hardware design that was never released. What exactly are you looking for?
Hi everybody im new in this and I need little help. Could someone sent me the PCB scheme of this. Thanks
Yes, but I'd refer you to the FMA site and documentation for more on that--it's not related to ArduPilot.
Do you just preset and test the cpd-4 in flight for the amount of stabilization?
Obviously a proportional channel is better.
No: the FMA co-pilot (AKA cpd-4) should be activated by a channel that has a proportional knob, so you can dial in the right amount of stabalization. The autopilot is simple on/off. So you need at least a 6 channel, ideally with at least one of the aux channels having proportional control. I use a Futaba 7C
The commercial boards will have the bootloader and ATtiny firmware pre-loaded, so all you'll need is a FTDI cable. But if you're rolling your own, you'll need an AVR programmer. More details are in this post.
Looking good. I have a question though. I'm making some headway with my Predator build and have decided an autopilot would be a great idea for safety if for no other reason.
I actually started ordering parts for the ArduPilot last night, but seeing this post now, I wonder if I should have waited. I even wonder if I should have waited for the Ardupilot Pro.
I have ordered this board
https://storage.ning.com/topology/rest/1.0/file/get/3689302195?prof... this still a valid part for the ArduPilot?
Is it possible to get a complete list of everything I need to build and use the Ardupilot through hole version? Do I need a programmer or can it be done from a computer?
Thanks
As for benchmarking the SCP1000 vs GPS, I'm still writing the code to do that on the Adafruit GPS logger Arduino shield. For some reason I'm having trouble getting my shield to work reliably, and between the SD-card logging code, the SPI code (for the SCP1000) and the analog sensor code, it's a beast of a software project.
What about expandability? For example I want to add the SCP1000 for potentially higher altimeter resolutions? (if you can give an idea just in general terms not in great details)
Thanks...
