Biostar introduced a trio of socket AM1 (FS1b) motherboards for AMD "Kabini" SoCs, the micro-ATX AM1MHP, AM1MH and AM1ML (pictured in that order). The AM1MHP features a narrow micro-ATX PCB, which draws power from a combination of 24-pin ATX and 4-pin CPU power connectors, and uses a 2+1 phase VRM to condition power. The AM1 socket is wired to two DDR3 DIMM slots, a PCI-Express 2.0 x16 slot, a PCIe 2.0 x1 slot, and a legacy PCI. A couple of SATA 6 Gb/s ports make for the storage connectivity. Display outputs include D-Sub and HDMI. Also included are legacy ports, such as COM and LPT, through headers.

Next up, are the AM1MH and AM1ML. The two are based on an identical PCB that's a variation of the the mini-ITX standard, in that it features a second add-on card slot, and differ only with the AM1ML lacking an HDMI port. Drawing power from 24-pin ATX and 4-pin CPU power connectors, the two offer PCI-Express 2.0 x16 and PCIe 2.0 x1 slots, and an otherwise identical feature-set to that of the AM1MHP.
