In terms of layout, it is 14 0.1" pins on each side, and at one end is a row of 5 0.1" pins (plus the row on either side for a combined length of 0.7"). Obviously the PCB is slightly bigger.
If you want access to the pins underneath the Teensy 3.0, there are breakout boards offered in Tindie that you could use, such as: https://www.tindie.com/products/loglow/teensy-30-breakout-mark-ii/?pt=directsearch or https://www.tindie.com/products/loglow/teensy-30-mini-breakout/.

Okay thank you
And I have another question, do you think I can use Teensy 3.0 to control 3 BLDC motorthree phase?
Because to control each motor I need 3 PWM so 3*3=9 the 3.0 got 10PWM
But I need that PWM can be dephased to 180° as http://m.eet.com/media/1045575/STMBLDCFig3.jpg and when I look the caractistics, I see that there are only two timer to generate PWM, so can i make 9PWM dephased 180° but with the same frequency ?
Thank you, and tell me if I need to make another post

PWM stuff is outside of my experience, so Paul or somebody will have to answer. However, there are some extension boards that can do multiple PWM. Lets see, the ones I know about off the top of my head include:
- Adafruit 12-channel, 16-bit PWM control using SPI: http://www.adafruit.com/products/1455. Note, you will need to power the chip with at least 5v, but it claims that you can drive it with 3.3v SPI logic. The documentation says it is more for LEDs and not for servos, so perhaps it isn't for you. There is a 24-channel 12-bit SPI version also available.
- Adafruit 16-channel, 12-bit PWM control using i2c: http://www.adafruit.com/products/815.
- Pololu 12/18/24 Maestro USB PWM control http://www.pololu.com/product/1353. Note, this is more setup for USB control of servos, and it has an internal scripting language that you setup on a PC. It is claimed you can drive it with 5v serial which means you would need to do level shifting to do 5v on the Teeny 3.0 and use one of the 3 hardware serial ports.
