There of course the omnipresent Arduino but this one looks really interesting as it has some clear advantages over the Arduino. The first one being the USB implementation, the Arduino has USB serial which way slower, the Teensy has access to the full 12 Mb/Sec while the Arduino tops out at a measly 38.4 kbps.

Now i don't know if that makes any real difference to speak of in real use, however the Teensy can act as a HID,Keyboard,Mouse even Midi device which means it'll work on any platform without drivers. So for a simple midi controller project you just plug it in the USB port and forget about it.

It is also relatively cheap, has lots of IO,it's really small etc.

Has anyone tried it ? Any cons i'm not aware of ?

They do look interesting, more I/O etc than an arduino so good choice for a midi controller perhaps.

Not sure about the usb speed, are you likely to build anything with a board like this that demands that kind of speed?

And just for the record, the latest arduino (Uno) uses a different chip for USB than earlier incarnations so can identify itself as a keyboard, mouse etc just like the Teensy.

I haven't used a Teensy but I use something very similar to program Dream DSPs and Arm processors (also made by Atmel). It's very handy to have the programmer integrated like that and Dream/Arm chips are much more powerful than the AVR Atmega chips.

The thing that's handy about Arduino is how it integrates with stuff like Max/MSP. I haven't found any similar tools for the Arms.

I seriously doubt that. It was more feeling of comfort knowing everything was running at full tilt should the need arise.

I did not know that,that's excellent. Does it run as class compliant midi device too ?

I thought it did but looks like you may need to fiddle with the firmware:

I guess keyboards etc are simpler to IF, midi needs a bit of help.

I have used the Teensy and love it. I saw a demo of it at Shmoocon this year by Iron Geek and purchased one right away. I posted an overview of getting started with it on my blog:

I am currently working on different ways to leverage it to pentest and bypass security protections. As far as cons go. The Arduino environment is a bit annoying after awhile and their built in libraries for Teensy are not well commented. If you are looking to get lower level then just leveraging the existing libraries in place.

Overall it is a great little device at a great price for playing with.

Nice!
Great find.

That looks really cool. It's been a long time since I built any electronics hardware. I might get back into that in the future.

Teensy - anyone tried it ?
