If you’re wondering exactly how the iPad Pro’s Pencil stylus works, a new look at its innards helps draw a clearer picture.</p><p>
Officially, we know the Apple Pencil connects to the iPad Pro via Bluetooth, and is not capacitive like a finger or generic stylus. Instead, it uses a pair of emitters to send angle and location data, and includes some
sensors inside the case for pressure detection.</p><p>
A
teardown by iFixit gives a little more detail: Inside the Pencil’s tip is a small metal bit, which likely connects to one of the two aforementioned emitters for angle and orientation detection. And inside the Pencil case, there’s a set of matching “ticks,” with three on the logic board and three on the pen assembly. iFixit guesses that these ticks help “sense pressure by measuring movement between these two parts.”</p><p class="jumpTag"><a href="/article/3006822/ipad/apple-pencil-teardown-reveals-tiny-logic-board-pressure-sensitive-trickery.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
