“Awesome alternative to Arduino. Needs headers for breadboard. I bought this to indulge a robotics urge after building a self balancing robot kit. Now I need all sorts of stuff like leds! Then I saw the audio library! I bought another teensy, and the audio plate. You need headers in a big way. To be compatible with other teensy, I put the headers on the teensy in the "normal" way. Problem is that on a breadboard, the audio plate needs to be clear of the bb so you can use the holes. You need to mount the teensy under the audio card using extended female headers. The way I have it with teensy on top, you need very tall headers to mount the plate on bb. This really, but really, needs a kit, and a build guide. Some issues with audio software, but the sound looks very promising. I would like to see a more feature audio board to make best use of potential.”
“Outstanding dev board with all the quality we know to expect from the PJRC team, and them some!
Hyper-fast @>600MHz for a board at this price-point, with amazing connectivity and packed with enough features to keep me satisfied for everything I've tackled - so far.
And the form-factor - "Teensy" it is indeed. The main "sacrifice" for this latest iteration of the family which comes in at ~1/2 footprint of the 3.6 is the loss of the SD card-slot, which is catered for (allegedly) by the inclusion of pads for an SD card interface using an SDIO (4 bit) native SD. I've yet to get close up and personal with this.
Interface with the Arduino IDE is seamless, and full compatibility with all of the libraries I've utilised so far - I've yet to find one that isn't supported...”
“Extremely powerful for the price- Lots of I/O in a very compact package. Best value for money of the Teensy variants.
Only gripe is the missing USB host functionality found in teensy 3.6/3.6.”
