Aaeon has posted specs for a Linux-ready “UP Xtreme” SBC with a 15 W, 8th Gen Whiskey Lake-U CPU, up to 16 GB DDR4 and 128 GB eMMC, 2x GbE, 6x USB, SATA and optional AI Core X modules via M.2 and mini-PCIe.
Aaeon’s community-backed UP project, which most recently brought us the Intel Apollo Lake based Up Squared and UP Core Plus SBCs, has announced an UP Xtreme hacker board built around Intel’s 8th Gen Whiskey Lake U-series Core processors. This is likely the fastest open-spec, community-backed SBC around, depending on your definition.

The only SBCs we’ve seen announced with the 14nm fabricated Whiskey Lake are Congatec’s 3.5-inch Conga-JC370 and thin Mini-ITX Conga-IC370. The Whiskey Lake U-series chips are notable for providing quad-core configurations with the same 15W TDPs of Intel’s earlier dual-core U-series chips. The quad-core models offer a performance increase of up to 40 percent compared to previous U-Series processors.
Aaeon appears to support all five Core i7/i5/i3 models, all but one of which are dual-threaded. The models range from the 1.8GHz (4.6GHz Turbo), quad-core Core i7-8565U to the 1.8 GHz (3.9 GHz Turbo), dual-core Core i3-8145U. Congatec clocks the latter’s base speed at up to 2.1 GHz, but Aaeon lists only 1.8 GHz base frequency for all the models.
The Whiskey Lake processors integrate Intel Gen9 UHD Graphics 620 with 24 EUs. They’re also notable for supporting USB 3.1 Gen2 with up to a 10 Gbps transfer rate. Sadly, however, the UP Xtreme does not include a USB 3.1 port, perhaps to reduce costs.
Even still, the board is not likely to make our under-$200 cut-off for the hacker board catalog. As noted in the CNXSoft post that first revealed the SBC, the lowest cost i3-8145 Whiskey Lake model sells for $281, suggesting the lowest Xtreme price might be about $350 to $400.
At 120 x 120mm, this is the largest UP board yet. The SBC supports up to 16GB DDR4 and up to 128GB eMMC. In addition to offering a powered SATA interface, there’s a SATA option on the M.2 “B/M” key slot, and mSATA is available via the similarly multi-purpose mini-PCIe slot, which is accompanied by a SIM slot. An M.2 Key E slot is also onboard.

The stacked HDMI and DisplayPorts will no doubt give you 4K video, and you can probably get triple 4K displays if you use the onboard 3DP header with backlighting. Audio headers are also available.
The UP Xtreme is further equipped with 2x GbE and 4x USB 3.0 ports, plus additional USB and RS232/422/485 headers. There’s also a pair of STM32 I/O headers, which may offer GPIO related to the STM32 MCU. Like other UP boards, further expansion is available via a 40-pin “HAT” GPIO connector, which suggests it can run some Raspberry Pi HATs.
AI Core X support
There’s no explanation for the 100-pin docking connector, which appears to offer four different options for I/O daughtercards (see spec list below). The UP Core Plus offers dual 100-pin connectors for various AI-enhanced add-ons such as the Cyclone 10GX-based AI Plus and the Myriad 2 based Vision Plus. However, the brief marketing copy on the UP Xtreme teaser page suggests that the UP Xtreme’s touted AI capabilities are instead launched via the M.2 and mini-PCIe slots.
