Description
Industrial Motherboard supporting the Intel® Core™ i3 processors &
Intel® processors N series
The Industrial Motherboard K3921-N mSTX is based on the latest Intel® Core™ i3 and Intel® Processors series (Alder Lake N) with powerful UHD Gen12 graphics using Intel® Xe architecture. There are two DisplayPorts 1.4, one DisplayPort via front USB-Type-C plus onboard connectors for Embedded DisplayPort and Dual-Channel 24bit LVDS panels. Three independent displays with up to 4K display resolution (2x 4K + 1x FHD) are supported. The K3921-N is equipped with two M.2 (Storage and Wifi) connectors and in addition to this offers many other connectivity options like GPIO, two COM ports and USB 3.2 Gen2. Designed and approved for 24/7 continuous operation and an enhanced temperature range up to 60 °C the K3921-N is applicable in many vertical markets.
