There are boards left in the shop www.flyduino.com
Got the BOBīs today, will solder some later this evening and ad them to the shop.
Its hard to say but it really sound like a bad connection or wiring.
Flyduino seems to work fine, power led is on and flashing "ftdi" Led means the code is running.
He reacts like if he didnt have any senors connected.
Please check connection to the sensors twice.
