The UAV Devboard is back in stock at SparkFun, with a new design.The reason for the design change is that Analog Devices no longer makes the gyro that we were using on the previous board, so we have switched the design to the LISY300AL. Paul Bizard and I have thoroughly tested the new board on fixed-wing aircraft, the LISY300ALs work just great with DCM.We have modified all of our existing firmware to be able to run on either board, and will make sure that all future firmware will also work on either board. If you have written firmware for the UAV dev board, you will only have to make a few minor changes to run it on the new one. The two board designs are nearly identical. The only differences are:1. The new board uses LISY300AL gyros instead of the ADXRS401, and the 6g range instead of the 1.5g range for the accelerometers. This will allow you to provide aerobatic control without saturating the sensors.2. The gyros, the accelerometers, and the A/D reference voltage are all tied to the 3.3 volt regulated supply. This will totally eliminate drift of gyros and accelerometers due to supply voltage changes.Each firmware project now has both a "green" version for the previous board and a "red" version for the new board.
The question only comes up if you are using either a PICkit2, or a PICkit3.
Every UDB is shipped with a 6 pin connector soldered into it for connection to a programmer/debugger. For a while, the connector was polarized, but that does not allow connection to a PICkit. So, a few months back, we changed the design to use an unpolarized connector, so that you can now connect a PICkit directly to the UDB. The UDB connector pins are male, the PICkit has a female connector.
However, lets say you do not want to connect the PICkit directly to the UDB, for example, if the UDB is mounted in your plane. Then you will need to buy a 6 wire cable, such as this one from SparkFun. However, the cable from SparkFun has a female connector on both ends. One end will connect ok to the UDB, but what about the other end? Well, you place this connector into the PICkit, and then you can connect the cable to the PICkit.
Hi Morli,
Thank you so much for helping Wong Chang. You are an expert.
Regarding the 6 pin ICSP connector, many pilots find it convenient to program their UDB while it is mounted in their plane. If they are using a PICkit2 or PICkit3, they will need a cable. The cables that you can easily get will need a connector, such as the ICSP connector, to connect the cable to the PICkit.
Best regards,

oh no, is all english..that's really hard for me to read that, but i need to do it..
we will try our best and really apprciate for u r help.Can i ask u more if i get some problem?
@John,
One more idea. I wonder if there are any "green board" owners who wished they had waited for the "red board" (for example, like Chris Anderson) who would be interested in selling a green board to you, and buying a red board from SparkFun to replace it. Maybe you could post a discussion to find out, if you want a green board. Just a thought.

Once again, I thank you for helping out. You have learned fast, I think you are one of the experts, now.

It seems I have confused things even more. Sorry.

is this one?
http://www.sparkfun.com/commerce/product_info.php?products_id=9038
can they ship to Taiwan?
and what is debugger? can i but in there too?
thanks a lot
i can't find sparkfun , is that a website? so where i can buty them toghter or in the same way??
sorry, just pool english...
You can buy the UAV DevBoard (UDB) from SparkFun for $150 US. You will also need a programmer/debugger with cable and connector, a GPS radio with cable.
You will probably want to read the information on the UDB website.
