A very fine product, in many ways 'just the ticket'. As any design, there are needed extensions. The use of I2C as the external interface and WiFi as the communications medium are, by themselves easy to work with and the Pico2350 is an excellent chip, but some access to the 2350GPIO would have been a nice thought. One answer is the IIC to Serial converter which works fine for Arduino but I have not been able to make it work on the presto under micropython. I like the touch colour screen (480x480) and Pimoroni give a good example software set, but I still yearn for some GPIO access. Great product, proud to own one!
