Picoware (Open-Source Custom Firmware)

[rockotiger]

It doesn’t come with one but this thread covers how people have been adding one:

RTC inside the case?

The one thing that would make the PicoCalc perfect for me would be to have an RTC attached (I have the Pico 2W in mine now). Has anyone looked at doing this? I think I’d have to solder to some of the headers to make it work, which is okay.

I’m going to order a WiFi enabled pico and then I can try out your online features.
