There are two DisplayPorts, one DisplayPort via front USB-Type-C plus onboard connectors for Embedded DisplayPort and Dual-Chan - nel 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) con - nectors 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.
