Which Teensy to buy

[paecific.jr]

I am looking to get a couple teensy boards for wiring up keyboards. One will become my Soarer's convert for AT. The other would be for a custom adapter for a Hall Effect keyboard. Which one? There are so many I am just lost.

teensy 2 is probably the easiest to work with

Awesome, thanks for the quick reply!

My experience with Teensy 3.2 is very positive as well. I wrote my own firmware (https://github.com/macroxue/keyboard-firmware) with Teensyduino (http://www.pjrc.com/teensy/teensyduino.html), which is Arduino IDE integrated with Teensy support.

Is there any reason apart from price not to directly just take an Arduino instead?

Interesting... I actually don't know how much an Arduino costs. When I googled DIY keyboards, all articles talked about Teensy so I bought Teensy. Then I learnt about Teensyduino and started to talked about Teensy as well. This is a positive feedback loop. I bet people use more Teensys than Arduinos for DIY keyboards and that's the trend moving forward.

teensy 2 with this https://github.com/tmk/tmk_keyboard is the easiest and most stable solution.

If you want you can also go with an Arduino micro (or one of the clones), which is very similar to the teensy 2. The only annoyance that I've noticed is that the bootloader is a pinch slower to boot.

Okay, so looking at my Hall Effect keyboard that I am looking to rewire. It has 32 pins. Thus I would need 32 digital inputs on my teensy right?

2 is supported by KB.sized.io for easy hand wireing and programming
