HackSpace journal concern 50 discusses the Adafruit ATtiny817 Breakout with Seesaw.
There are actually a whole lot of improvement boards to select from, with a mind-blowing vary of processors, reminiscence, storage, pin rely, and measurement. Why is it, then, that we at all times appear to be lacking a characteristic once we get to our initiatives?
Typically it’s as a result of we begin with one design and maintain including bits till we run out of pins; different occasions, it’s as a result of we use the dev board we now have readily available fairly than probably the most appropriate one.
Luckily, there’s a inventory of elements that may assist us. Port expanders, I2C analogue-to-digital converters, and extra could be tacked onto most microcontrollers to offer us the additional options we’d like.
Enter the Adafruit ATtiny817 Breakout with seesaw. That is principally a configurable STEMMA QT/Qwiic to virtually something bridge. If you wish to add digital I/Os, there are 14 you should use. 9 of them can be analogue inputs, and 5 could be PWM outputs.
What we like about this board, although, isn’t the specs; it’s how simple it’s to make use of. Simply plug it in by way of the STEMMA QT/Qwiic cable and it’s all arrange. There are libraries for CircuitPython and Arduino, so you may get it engaged on most maker-level {hardware}.
