ASRock's lineup of compact Braswell motherboards isn't just limited to the embedded-oriented offering we spotted last month. The company's website now details seven more conventional models based on the 14-nm Bay Trail sucessor. All of them cool the low-power chip with a passive heatsink, and there's a fair bit of variety within the family.
Three microATX boards are available with different variants of the SoC. You can choose between one quad-core chip, the Pentium N3700, and two duallies, the Celeron N3150 and N3050.
Apart from the processors, the microATX boards appear pretty much identical. They have full-sized memory and expansion slots, including a PCIe x16 limited to a single lane of Gen2 bandwidth. Other amenities include dual PCIe x1 slots, dual SATA ports, and USB 3.0 for the front and rear.
The Mini-ITX flavors switch to smaller SO-DIMMs. Expansion is limited to mini and full-sized PCIe x1 slots, but a couple of the boards actually have more ports than their microATX siblings. The N3700-ITX and N3150-ITX add two more SATA ports via an ASMedia chip, plus DisplayPort output and extra audio jacks. I'll let you guess which one has which CPU.
In addition to the beefed-up Mini-ITX boards, there's also a couple of stripped-down variants limited to dual-core Celerons. This effective B-team trades modern ports for serial and parallel connectors that probably won't be of interest to most of you.
