NUC-155H R2 Thin Mini-ITX Motherboard

Description

The NUC-155H R2 is an industrial Thin Mini-ITX motherboard with Intel Core Ultra 7 155H (Meteor Lake-H), Intel Arc Graphics, DDR5, dual 2.5G LAN, 2x HDMI 2.1 and Intel vPro for the most demanding AI edge and embedded applications.

The ASRock Industrial NUC-155H R2 is based on the Intel Core Ultra 7 155H (Meteor Lake-H, 6P+8E+2LPE cores) with the powerful integrated Intel Arc Graphics (8 Xe cores) and an integrated NPU for AI acceleration. The board supports Intel vPro and offers up to 96 GB of DDR5-5600 MHz memory via two SO-DIMM slots.

The storage configuration comprises two M.2 Key M slots (PCIe Gen5 x4 for 2280 and PCIe Gen4 x4 for 2242/2260/2280), RAID VMD support and one SATA3 port. An M.2 Key E slot (2230) allows optional WLAN/BT modules via CNVi or PCIe.

Connectivity: 1x USB4/Thunderbolt 4, 4x USB 3.2 Gen2, 2x USB 2.0 internal and dual 2.5G LAN (Intel I226LM with vPro + I226V). Video outputs: 2x HDMI 2.1 TMDS and DisplayPort 2.1/1.4a via USB4 – suitable for demanding multi-display configurations.

The board is designed for operating temperatures from -20 °C to +70 °C and features Intel PTT (TPM 2.0), hardware watchdog and AT/ATX power-on modes with 12–24 V DC input voltage – ideal for AI edge computing and high-performance industrial applications.
