The Teensy USB development board from PJRC has been upgraded to a new board featuring Atmel’s newer ATmega32U4 device. With this comes the benefits of the new device, including A/D channels, extra I/O (including PWM and I2C) and more memory. By default it operates at 5v, but it can be converted to operate at 3v3, a very nice feature for interfacing with modern peripherals. Even with the additional pins and functionality, it’s just as small as the original Teensy. Great work, Paul!
And the best part… the new Teensy board is even cheaper than the old one. Now the price has been dropped to just $18 (or $21 with pins.) I’m certainly planning on ordering one.
Also of note, the Teensy 2.0 is now available for order from Adafruit Industries. This should boost product awareness and get this great board into the hands of more developers.
