PJRC is the manufacturer of Teensy, which is a high-powered alternative to Arduino. It’s compact, adaptable, and offers fantastic value for money. The Teensy works well with sensors which output large amounts of data with a fast refresh rate. It’s also relatively easy to get the Teensy to work with touch-screens, mice, and keyboards, which makes getting input into the chip straightforward. Moreover, the chip allows DMA (Direct Memory Access) for speeding up processing time by algorithms that require fast processing (Led strips, Screens, Audio and Movement/Orientation).
