Aaeon reveals Elkhart Lake Pico-ITX and ships Tiger Lake 3.5-inch SBCs

Nov 3, 2021 — by Eric Brown 402 views

[Updated: Nov. 4] — Aaeon has announced a previously teased, Intel Elkhart Lake based “PICO-EHL4” Pico-ITX board and has launched its 3.5-inch, Tiger Lake-U based GENE-TGU6 SBC with 2.5GbE and quad display support, starting at $717.

Yesterday, when we were reporting on Canonical’s release of Ubuntu images optimized for Intel’s Elkhart Lake and Tiger Lake processors, we saw several patch notices referring to the EHL. Aaeon then confirmed that the patches referred to its PICO-EHL4 SBC, which was revealed with no image and very few details a year ago after Elkhart Lake was announced. Aaeon has since posted specs, apparently in late September when it announced the board, on Aaeon’s newsletter. [Update: Aaeon announced the PICO-EHL4 on Nov. 4, a day after this post was originally published, but did not reveal any new information.]

We also cover Aaeon’s Tiger Lake-U based GENE-TGU6 3.5-inch SBC, which we detailed in May based on a preliminary product page and which Aaeon has now formally launched with some minor changes.

We were confused by Canonical’s mention of a bug fix for the PICO-EHL4 for the Intel I225-IT 2.5GbE Ethernet controller, since the PICO-EHL4 is listed only with dual 1GbE ports based on Realtek’s RTL8111H. Aaeon then informed us that an upcoming, UP-branded, community backed variant of the PICO-EHL4 will indeed supply the 2.5GbE I225-IT.



The PICO-EHL4 follows earlier Aaeon Pico-ITX boards such as its Apollo Lake based PICO-APL4. Other Elkhart Lake based Pico-ITX boards include Vecow’s EPCB-1000 and Congatec’s Conga-PA7.

The PICO-EHL4 runs Ubuntu or Win 10 on a choice of dual- or quad-core Atom X-6000 “E” and “RE” processors up to a quad-core, 1.8GHz/3.0GHz Atom x6212E. There are also several Pentium and Celeron SKUs, and a quad-core Atom x6427FE or headless, dual-core x6200FE are available by customer request. The RE models add Intel’s TCC and similar TSN synchronized networking features while the FE also adds Intel Safety Island functional safety (FuSa) features.

As with the Conga-PA7, you can load up to 16GB LPDDR4 at 3200MHz per the spec sheet and 4267MHz per another citation. (Vecow’s EPCB-1000 supports 32GB.) Storage features are a cut above the competition, with up to 64GB eMMC, SATA with power, and a mini-PCIe slot that defaults to mSATA.

The PICO-EHL4 supplies dual HDMI ports and either LVDS or eDP, depending on the SKU. The Celerons and the dual-core Atom x6211E get the LVDS while the others get eDP. For communications, you get the dual GbE ports and an M.2 E-key slot that supports WiFi/BT.

As with the Conga-PA7, there are 2x USB 3.1 Gen2 ports rather than the slower Gen1 with Vecow. In addition to offering USB 2.0, serial, DIO, and other headers, you get two standard CAN headers, which are optional with Congatec, and there is an optional CAN board.

The SBC does not offer the M.2 B-key slot available with its rivals, or Vecow’s SIM card slot. The board also lacks the standard (Vecow) or optional (Congatec) extended temperature support.

Specifications listed for the PICO-EHL4 SBC include:

  • Processor – Elkhart Lake Atom “E” and “RE” plus Pentium and Celeron with 2x or 4x 10nm Elkhart Lake cores @ up to 1.8GHz/3.0GHz (Atomx6425E); 6.5W to 12W TDPs; Intel UHD Graphics (Intel Gen11); built-in Cortex-M7
