The Celeron J1800 CPU supports six USB 2.0 ports and one USB 3.0 port. The ASRock D1800B-ITX offers five USB 2.0 ports, three at the rear panel and two available through a header located on the motherboard, and one USB 3.0 port at the rear panel.

The motherboard does not support FireWire or Thunderbolt ports.

The motherboard supports 5.1 audio format, generated by the processor with the aid of a Realtek ALC662 codec, which offers a signal/noise ratio (SNR) of 98 dB for the analog outputs and 90 dB SNR for the analog inputs, with 24 bit resolution and up to 96 kHz sampling rate. These specifications are reasonable for the market this motherboard was designed.

The portrayed motherboard has one Gigabit Ethernet port controlled by a Realtek RTL8111GR chip.

One thing that drawn our attention was the presence of legacy serial and parallel ports at the rear panel. This means this motherboard is also target to application computers such as POS, cash register, ticket emitter, access control, and other applications where legacy industrial or commercial specialized hardware is needed. The motherboard comes with a second serial port (COM2), which needs an adapter (not included) to be used.

In Figure 5, you can see the motherboard rear panel with two PS/2 connectors for keyboard and mouse, serial port, parallel port, VGA output, three USB 2.0 ports, HDMI output, one USB 3.0 port, Gigabit Ethernet port, and the shared analog audio jacks.
