Description
F5120-V243 Kontron K3921-H mini-STX Intel Processor N100 QC 6W TDP Motherboard
The K3921-H1 is engineered for demanding environments, including industrial automation, digital signage, medical devices, and embedded computing. Its fanless design, extended lifecycle support, and robust I/O make it suitable for applications requiring reliability, high-performance graphics, and flexible connectivity.
The Extended Lifecycle mSTX Motherboard K3921-H is based on the latest Intel® Core™ i3 and Intel® Processor series (Alder Lake N, Twin Lake) with powerful UHD Gen12 graphics using Intel® Xe architecture. There are two DisplayPorts 1.4 and one DisplayPort via front USB-Type-C plus onboard embedded DisplayPort. Three independent displays with up to 4K resolution (2x 4K + 1x FHD) are supported. The K3921-H is equipped with an M.2 Key-M connector with PCIe and SATA support and in addition to this an M.2 slot for WLAN/Bluetooth modules (PCIe and CNVi) and other PCIe based add on cards is also included. Via the front USB-Type-C the K3921-H supports PowerDelivery Sink mode, USB 3.2 Gen1 and DisplayPort AlternateMode (DPoC). This makes it the perfect fit for Thin Client applications, in combination with our very compact SMARTCASE™ S501 chassis. All components are designed and approved for 24/7 continuous operation.
