This is NOT another Arduino package but a rather impressive 48 MHz, 32-bit ARM computer, with 10 PWM outputs (think servos), I2C capability, 16-bit A/D, etc. Methinks that Teensy 3.0 is a *natural* for DIY RC on-board data-collection, autopiloting, and Return To Launch failsafe systems.

Earlier Teensy boards used AVR chips, and, with the USB interface, were programmable using Arduino IDE, a rather pain-free interface for the inexperienced user. Teensy 3.0, although based on an ARM chip, arranges to use a modified Arduino IDE, which should make this device a quick-start for AVR users. If you know Arduino at all, the much smarter Teensy 3.0 should be a big, easy, and affordable step up in power.
Arduino libraries in general will not work with Teensy 3.0. However, such a large base of open-source code should make this a fun area for tinkerers, at least with my primitive level of experience.
Altimeters, GPS, temperature sensing, and servo control all are a snap with Arduino, of course. I'll be interested to see what can be done with this new device.
If anyone asks, I'll be out by the mailbox waiting for my new Teensy 3.0 to arrive...
