Yes, the Angelbird AV PRO SD V90 128GB is compatible with the Canon EOS R3.
Canon EOS R3 Slot 2 accepts SD UHS-II. Angelbird AV Pro V90 writes at 280 MB/s (V90) — meets all SD-recordable modes on the R3 including 4K 29.97fps ALL-I (requires V60) and Full HD 239fps slow-motion (requires V90). 6K RAW and 4K 120fps HFR are CFexpress-only and unaffected.
“[200 MB/s or higher] Video Speed Class V90 or higher”
