Fujitsu D3543-S2-J4105 2xDP/GBL/M.2/mITX+++ - Mainboard

The Fujitsu D3543-S2 is a Mini-ITX industrial motherboard built around the energy-efficient Intel Celeron J4105 quad-core processor, delivering reliable performance for always-on embedded systems. Its compact 170 x 170 mm footprint and fanless-capable design make it ideal for space-constrained applications such as digital signage, thin clients, and kiosks.

Advantages

The integrated Intel UHD Graphics 600 engine drives dual DisplayPort 1.2 outputs and a DVI-D port, supporting high-resolution displays without a discrete GPU. The board includes dual Gigabit Ethernet via Intel I210AT controllers, ensuring stable network connectivity for critical tasks. Expansion is flexible with two M.2 slots (Key M for storage, Key E for wireless) and an open-ended PCIe x1 slot.
