The motherboards offer scalability in terms of performance, power consumption and cost within one product design and are available in four variants with different CPUs at

Kontron recently awarded Rutronik the title of "Best Motherboard Distributor" once again. Especially the consulting services, the reliable supply of existing customers, and the acquisition of new customers were highlighted. Equipped with the latest UHD Gen12 graphics, they use the same efficient cores based on the Xe architecture. In combination with up to 32 execution units, accelerated deep learning inference and media processing for various edge applications are supported by Intel® AVX2 and Intel® Deep Learning Boost.

With up to three display ports V1.4a, one embedded display port V1.4b (4K) and one dual-channel LVDS (24 bit), the boards support a maximum of three independent displays with 4K resolution. In addition to interfaces such as GPIO, four COM ports and four USB 3.2 Gen2, the Alder series has expansion slots for PCIe and two M.2 ports.
