Description

The NUC-125H R2 is an industrial Thin Mini-ITX motherboard with Intel Core Ultra 5 125H (Meteor Lake-H, 4P+8E), Intel Arc Graphics, DDR5-5600, dual 2.5G LAN, Thunderbolt 4 and Intel vPro for demanding AI edge and industrial applications.

The ASRock Industrial NUC-125H R2 is based on the Intel Core Ultra 5 125H (Meteor Lake-H, 4P+8E cores) with integrated Intel Arc Graphics. The board supports up to 96 GB of DDR5-5600 MHz memory (dual channel) via two SO-DIMM slots, offering exceptional performance reserves for AI-powered applications.

For data storage, two M.2 Key M slots (PCIe Gen4 x4) and one SATA3 port are available. Intel VMD RAID 0/1 is supported via identical PCIe interfaces. An M.2 Key E slot (2230) allows optional WLAN/BT modules.

Connectivity comprises 1x USB4/Thunderbolt 4, 4x USB 3.2 Gen2, 2x USB 2.0 as well as dual 2.5G LAN (Intel I226LM + I226V). Video outputs: 2x HDMI 2.1 TMDS (rear), 1x DP 2.1 (via USB4) and 1x DP 1.4a (via Type-C) for up to 4 displays in total. COM port RS-232/422/485.

The board is designed for operating temperatures from -20 °C to +70 °C and features Intel PTT, a hardware watchdog timer and AT/ATX power-on modes with 12–24 V DC input voltage – ideal for Intel vPro remote management and AI workloads.
