ASRock introduced a trio of low-cost embedded motherboards for entry-level desktops based on Intel's newest 14 nm "Apollo Lake" Pentium/Celeron SoCs. These include J3455-ITX and J3455M based on the Celeron J3455 quad-core SoC; and the J4205-ITX, based on the Pentium J4205 quad-core SoC. The J3455-ITX and J4205-ITX are based on a common board design, differing only with the SoC, while the J3455M features a narrow, 3-slot micro-ATX design.

The J4205-ITX and J3455-ITX take in power from a 24-pin ATX connector. The SoC is wired to two DDR3L SO-DIMM slots, supporting up to DDR3-1866 MHz spec. Expansion slots include one PCI-Express x1, and an M.2 (PCIe x2 electrical) connector. Besides this M.2, storage connectivity includes four SATA 6 Gb/s ports. 8-channel HD audio, gigabit Ethernet, and four USB 3.0 ports complete its connectivity. The J3455M features a PCI-Express 2.0 x16 (electrical x1) besides two other PCIe x1 slots, and features two standard DDR3 DIMM slots instead of SO-DIMM; and features 6-channel HD audio instead of 8-channel. The rest of its connectivity is the same as its ITX siblings.
