There are "commercial" boards, but they price by appointment only and probably cost 3-10x as much. Here's an IO comparison Udoo Bolt * 1 sata 3 port * 1 m.2

There are "commercial" boards, but they price by appointment only and probably cost 3-10x as much. Here's an IO comparison Udoo Bolt * 1 sata 3 port * 1 m.2 type B (2x PCIe 2 lanes) * 1 NVME drive (over 4x PCIe 3 lanes) * 1 eMMC 5 (32gb soldered -- a mistake IMO, but one could potentially solder on a different chip) Rockchip rk3399 (raw specs) * 1 eMMC 5.1 * 2 SD/MMC 4.5 * 4x PCIe 2.1 lanes The Helios64 is stretching all their SATA across those 4x PCIe 2.1 lanes. The single m.2 type B on the udoo has that much bandwidth by itself (and the NVME has the equivalent of 8x additional PCIe 2 lanes). If you really wanted, you could probably find an adapter that could turn the NVME into PCIe and then into quite a few SATA lanes as that's basically all they're doing anyway with the helios.
