In fact, recently the Chinese manufacturer Onda launched H610M +, a micro ATX motherboard with an eight-phase power subsystem, which supports Alder Lake processors up to Core i7 models and is equipped with a DDR4 and a DDR5 slot. Despite the obvious limitation, the product is capable of accommodating DDR4-3200 and DDR5-4800 modules with a maximum capacity of 32GB. The exact operation of the card has not been specified, but it seems reasonable enough to think that it is only possible to use one slot at a time.

As for the rest of the technical specifications, the card offers a PCI Express 5.0 x16 slot and a PCI Express x1 slot for expansion, as well as three SATA III ports and an M.2 PCIe 3.0 x4 slot for SSDs (and an additional M.2 slot for Wi-Fi adapters). On the rest we find a PS / 2 combo port, two USB 3.0, two USB 2.0, one Gigabit Ethernet and three 3.5m audio jacks, while on the motherboard itself there are USB 2.0 and USB 3.0 headers for adding two more USB 2.0 and USB 3.0 ports. Finally, to take advantage of the integrated GPU in the processors, we would like to point out the presence of VGA and HDMI video outputs.
At the moment, Onda H610M + is still on sale; therefore, we don't know its price yet, but it will probably hit oriental store shelves soon.
