“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.”
