How to update the card

Take the card out of your gear (on the SP-202, just switch it off), and plug it into your computer with a USB-C cable.
Open the page on the card, Generic Card Manager or the SP-202 Card Manager, in Chrome or Edge (Firefox 151+ works too). Under FIRMWARE UPDATE, press CHOOSE .UF2 and pick the firmware you downloaded.
Press CONNECT, then UPDATE, then COPY TO RP2350 and pick the drive named RP2350. The card restarts with the new firmware. Everything stored on it stays there.
