Fatal1ty B450 Gaming-ITX/ac on the asrock website says it only has 1 m.2 and I have bought it and used it for a friends build and can confirm it only has 1 slot
The motherboard has 1x m.2 M-key for storage and 1x m.2 E-key for wifi/bluetooth
I own this motherboard and the Wifi/Bluetooth module seems to be on the main board. The M-key m.2 slot is on the backside of the board, where would the E-Key M.2 slot be?
The Wifi/Bluetooth module is an m.2 E-key.
Per the spec page:
Ahh, I see, it's inside the metal bracket for the antennas. https://i.imgur.com/ekLYjPG.jpg
Thx. Never would've guessed that you could hide an m.2 slot there.
