Nexcom X100-J3455-P 3.5″ SBC with Intel Celeron J3455, HDMI, LVDS and Mini-PCIe with SIM

A portable terminal, multimedia panel or thin client runs from a battery or a small adapter, so the board has to draw little power and still drive its own display. The X100-J3455-P is Nexcom’s 3.5 inch SBC on the Intel Celeron J3455 for that kind of design, with an HDMI output, an LVDS panel interface and a choice of 12 V or 19 V DC input.

The onboard Intel Celeron J3455 is an Apollo Lake processor with a 10 W TDP, which suits thin-client sessions, home automation and panel software. One DDR3L SO-DIMM socket takes up to 8 GB. HDMI runs at up to 4096 x 2160 at 60 Hz, and an 18/24-bit LVDS interface drives a panel at up to 1920 x 1200, with inverter, backlight and power headers and a 4-way switch to set the panel resolution, so one board runs a built-in screen and an external monitor.

I/O covers two Gigabit Ethernet ports on Realtek RTL8111H controllers with wake on LAN, two USB 3.0 and two USB 2.0 ports, one RS-232/422/485 port on a D-SUB 9 connector and one RS-232 port on a JST connector, and Realtek ALC3236 audio with a line-out header. Storage is an M.2 2242 Key M socket, and a full-size mini-PCIe slot supports Wi-Fi and LTE modules with a full-size SIM slot onboard. A watchdog timer is included. The X101-J3455-E is the same processor with two HDMI outputs and eDP, and the X102 moves to Intel Alder Lake-N with two 2.5GbE ports.

Power is 12 V or 19 V DC, with AT or ATX mode set by jumper. The X100-J3455-P operates from 0 to 60 °C ambient and handles 10 to 90% operating humidity and 5 to 95% non-operating, non-condensing. The board measures 146 x 102 mm in the 3.5 inch form factor and carries CE and FCC Class A marks. Nexcom does not list operating systems for this board on the datasheet.
