There's still the Teensy 2.0/3.0 which is smaller & cheaper than this board. The Teensy 2.0 ($16) uses the same chip (32u4) as the arduino micro, and the 3.0 ($19) uses an arm-m4 chip which also provides a DSP. The best thing about the Teensy is that it's available right now.
- ippisl 14y agoIs the teensy 3(arm) fully compatible with all the arduino libraries ?
- catch23 14y agoYes and no. Even some arduinos are incompatible with certain arduino libraries. Most of the libraries were written for the most popular 328p chip at the most popular frequency (16mhz), but if you're using a Due or Attiny or even the 328p running a different frequency, you may need to touch up the libraries to get it to work. My guess is the compatibility levels would be similar here. Most people are probably only aware of the arduino uno which uses the 328p chip, but there are probably 20 other atmel chip models that are also "arduino compatible". I typically use the attiny85 because my one-off projects rarely need all the pins on the 328p.
- skreech 14y agoTeensy 3.0 looks awesome. Do you know anything similar with a radio?
- Shrugs 14y agoThe Wixel seems to be similar, but with built in wireless. http://www.pololu.com/catalog/product/1336 http://www.pololu.com/catalog/product/1336
- jws 14y agoLooks like a 30kbps radio on a serial interface, 256 channels in the 2.4GHz band, 50 foot indoor range typical. $20 for µcontroller with radio.
- pygy_ 14y agoThe teensy 3.0 also comes with a 16 bit ADC (of the succeessive approximation breed, not sure of the quality). Most of the arduino-like boards have a 10 bit resolution.
- dkersten 14y agoI've been using Teensy 2 for about a year and they're awesome!
