Description

The NUC-6305E is an industrial Thin Mini-ITX motherboard with Intel Celeron 6305E (11th Gen Tiger Lake-UP3), dual-channel DDR4, dual Gigabit/2.5G LAN and extensive connectivity for demanding embedded applications.

The ASRock Industrial NUC-6305E is based on the Intel Celeron 6305E (dual-core, 11th Gen Tiger Lake-UP3) at 1.8 GHz and the integrated Intel UHD Graphics. The board supports up to 64 GB of DDR4-3200 MHz memory via two SO-DIMM slots, providing a solid foundation for cost-sensitive industrial and embedded applications.

For data storage, one M.2 Key M slot (PCIe Gen4 x4/SATA3, 2242/2260/2280) and one SATA3 port are available. An additional M.2 Key E slot (2230) allows the optional integration of WLAN/BT modules via CNVi or PCIe.

Connectivity includes 1x USB4/Thunderbolt 4, 5x USB 3.2 Gen2 and 2x USB 2.0, plus dual LAN (Intel I219V 1G + Intel I225LM/V/I226V 2.5G). HDMI 2.0a and DisplayPort 1.4 (DP++) are available for video output; two further DP 1.4 outputs are supported via the Thunderbolt 4 and USB-C ports, so that up to four displays can be operated simultaneously.

The board is designed for industrial operating temperatures from -20 °C to +70 °C and features a hardware watchdog timer, TPM 2.0 onboard IC, AT/ATX power-on modes and a 12–19 V DC input voltage – ideal for rugged industrial and digital signage applications.
