Asus TUF B550M-PLUS (WI-FI) Schematic
For external connectivity, it also has both analog and digital audio outputs, 2.5Gb Ethernet, WiFi 6, Bluetooth, eight USB ports of varying speeds (including one Type C), and even a legacy PS/2 port.
A couple of oddities about this board are worth noting, but shouldn't impact most users:
- The HDMI and DisplayPort connections on this motherboard are for CPUs with built-in graphics, but the higher-end Ryzen chips we carry don't support that feature (since almost everyone uses a dedicated video card)
- The onboard NIC does not support Linux, so users of that OS will want to have a dedicated network card added
