  • If you update the firmware on the Pico the RTC gets a bit more accurate, but yes, it's not great.

    You can add a crystal - you just need:

    • An Abracon ABS06-107-32.768KHZ crystal (the '107' bit in the part number is important)
    • 2x 4pF 0402 capacitors (however you could initially try without fitting these - the capacitances are so low I'm not 100% sure you need them)

    The arrangement is exactly the same as on the Espruino WiFi (where there is a crystal), so you can see how they're fitted on to the pads on the end of the board there.
