Booz PCB available now: Re: [Paparazzi-devel] Questions on Booz hardware

[David Conger]

Angus,

Yes, PCB for the Booz and IMU are available from ppzuav.com
- IMU: http://ppzuav.com/osc/catalog/product_info.php?products_id=100
- (I will add the booz and gps PCB today).
Orders for PCB will ship next day as they are quick to put in a padded  
envelope and ship.
Assemblies are on the way. Flying these current designs will help  
direct the new designs.

Regards,
David Conger
