Does USB 3.0 meet the basic needs of your daily requirements? Yes. Are two onboard USB 3.0 ports more than enough? Sometimes no. In addition to a USB mouse, keyboard, flash storage, and other gadgets, more USB interfaces definitely bring richer application scenarios and imagination.
For example, DIY a garden surveillance camera, collect real-time factory control equipment data using USB to RS485, or build an intelligent voice assistant with a USB microphone. In addition to scalability, power supply stability is a must for a PCIe module.
- PCIe x1 Interface (compatible with PCIe x1 x4 x8 x16)
- 4x independent power supply
- 4x independent fuse
- Interface speed up to 5Gbps
- Compatible with Windows/Linux
- 1x PCIe to 4 Channel USB Adapter
My usecase for the ZimaBoard is to trim NVME SSDs that I use (mostly) in USB enclosures (which don't pass trim command). With the ZimaBoard, I can use a passive 4x PCIe to M.2 adapter to directly connect the SSD, and I don't have to open a PC/laptop/miniPC.
- external PCIe slot
- passive cooling
- dual LAN (irrelevant for my use)
- outdated CPU
- PCIe 2.0 (not a con for me)
- miniDP display port (yeah....don't really see space for a full HDMI, unless an ?expensive? vertical one. Mini/microHDMI would also be cons...maybe just neutral).
