Conclusive engineering indicates that mainstream Linux is supported, FreeBSD 13 support is available upon request, and U-boot, UEFI EDK2, and Arm Trusted Firmware are also supported. There should eventually be a customer portal and wiki with “manuals, datasheets, pre-built OS images, and other useful information”, but all of this is currently displayed as “Coming soon“.

The WHLE-LS1 network SBC is offered with a 16 GB eMMC flash directly from the company store for prices ranging from $399 to $579 depending on the selected processors. The announced deadline is 14 weeks. More details, including a 54-page datasheet, can be found at the product sheet.
