+Open-source security key firmware for the Raspberry Pi Pico 2 (RP2350): FIDO2/WebAuthn and U2F,
+OpenPGP card, PIV, OATH and OTP slots in one composite USB device (FIDO HID, keyboard HID and
+CCID), built on pico-fido and pico-openpgp. A dedicated ID lets pcscd/libccid recognise the key's
+CCID interface out of the box, instead of the shared test PID 1209:0001. Later revisions add an
+NXP SE051 secure element and an open board design.
