Is a CAN Transceiver needed for a NUCLEO-F446RE?

That's basically it.  I'm thrown off because this page explicitly says it has a 'CAN FD Transceiver', however, nothing says CAN on the silkscreen and this graphic I found:

Refers to the D14 and D15 pins as "CAN TD" and "CAN RD", which I assume is TX and RX implying that I would need a transceiver (CAN uses CAN High and CAN Low).

 

Am I right in understanding that I need a MCP2551 or similar transceiver despite what the product description page says?

Yes, the latest MB2046 for STM32C092 supports FDCAN.

Thanks for the feedback everyone - Sounds like my understanding is correct.  I do think the product page was very misleading, I actually chose this NUCLEO board just because I thought it had a transceiver, but at least I figured it out.
