“Totally neccessary adjunct to the Pimoroni Presto, it gives IO capability that is not provided by the original device, working through the I2C interface. Works well, have not yet established speed capabilities but very welcome just the same.”
“I bought this to add digital IO pins, ADC input and PWM output to my Presto which has only I2C for Input/Output. It is really easy to connect and I've found it to be really useful.”
“A quick and simple way of adding additional GPIOs and some ADC channels to a raspberry pi (which it misses otherwise). Really simple to use with Python on the Pi using the excellent breakout garden HAT. I love the whole breakout garden range - it's such a simple but excellently executed idea that makes quick prototyping of inputs and outputs from the Pi and Pi Pico a simple case of plugging the cards into the base and writing some code to glue them all together.”
