The BOXER-8651AI-PLUS is relatively compact at 125 mm x 90 mm x 56 mm, with its I/O including four USB 3.2 Gen 2, one RJ-45 for Gigabit Ethernet, and a HDMI port on its front-side for easy access. Meanwhile, its rear I/O grants both a DB-9 port for both RS-232 (Rx/Tx/CTS/RTS) and CANBus FD, and a DIO port. For expansion, the BOXER-8651AI-PLUS hosts an M.2 3052 B-Key for an M.2 2242 B+M-Key SSD, which acts as the system's default storage option, while this can also support 5G module installation. Alternative wireless expansion can be found in the form of an M.2 2230 E-Key slot, designed for Wi-Fi module integration, as well as through a SIM card slot.
