New to the Store: Teensy 3.1

New today in the Hackaday Store is the Teensy 3.1. This development board blows away most others in its class. The board plays nicely with the Arduino IDE, but embedded developers who are hardcore enough have the option of bare metal programming for the Coretex-M4 chip.

Why would we say this blows most others away? In our minds, the 64k of RAM and 72 MHz clock speed place this far outside of what you would normally see hanging out in the Arduino ecosystem. That may be changing with new players like the Edison, but the Teensy 3.1 doesn’t require a host board and comes in just under $20 compared to the Edison’s $50 price tag.

[Paul Stoffregen], the developer of the Teensy, is a hacker’s hacker and is known to be found round these parts. All year [Paul] has been developing an Audio Library that takes advantage of the Teensy 3.1’s powerful processor (including its DMA features; we’ve been pestering him to write an article for us on that topic). We covered the library back in September and are stocking the audio add-on board in the store as well. Quite frankly, the quality of sound that this puts out is astonishing. If you’re working on a project that calls for playback of recorded sound this is one of the least-complicated ways to get there.
