K3881-C

Kontron K3881-C μATX Industrial Server motherboard features the Intel^® C266 chipset with enterprise-grade Intel^® XEON^® 6300 series, XEON^® E-2400 series, and Pentium^® Gold G7400T/G7400 processors.

The K3881-C represents the first industrial server motherboard designed and manufactured in Germany by Kontron, incorporating custom BMC development with ASPEED A2600 controller for enhanced remote management and security. Server-grade capabilities include up to 128GB DDR5-5600 ECC memory across four UDIMM slots, dual Intel® E610 10GbE ports with BMC sharing, and dual Intel^® i210 Gigabit Ethernet with advanced teaming and Wake-on-LAN support.

Expansion and connectivity options are comprehensive for industrial server deployment. Three PCIe slots provide Gen5 x16, Gen4 x4, and Gen4 x1 configurations with bifurcation support, while dual M.2 2280/22110 slots accommodate high-performance NVMe storage. The MCIO connector enables flexible expansion with either 4x SATA drives or PCIe Gen4 connectivity, complemented by dedicated M.2 slots for 5G wireless modules and WiFi/Bluetooth connectivity.

The integrated management subsystem delivers enterprise-grade remote administration through Kontron Open BMC firmware, supporting IPMI and Redfish protocols with dedicated management LAN port. ASPEED 2600 graphics provide DisplayPort 1.1a output for local console access, while comprehensive monitoring includes SMBus, PMBus, and SGPIO interfaces alongside eight-bit GPIO expansion.

Designed for 24/7 continuous operation with extended 5+ year availability, the K3881-C supports Windows Server 2022/2025 and Linux-64 operating systems. The compact μATX form factor accommodates space-constrained industrial environments while maintaining full server functionality.
