Class-Leading Performance-ROCK Pi has a modern and powerful hexa-core ARM based RK3399-T Soc, All models are equipped with LPDDR4 3200Mb/s RAM and optional high performance eMMC modules
IO performance-ROCK Pi development board comes with multiple storage options and providing read and write performance on external storage drives. This improves workflow, copying, backups and overall file usage
Maker Friendly, IoT Connectivity-ROCK Pi features maker friendly expansion options, including a 40-pin GPIO interface that allow for interfacing with a range inputs from buttons, switches, sensors, LEDs, and much more
Multi Storage eMMC module-Optional industrial compatible high performance eMMC module, 16G/32G/64G/128G available, TF card slot supports up to 128G; M.2 connector supports up to 2T M.2 NVME SSD
AI Capabilities- ROCK Pi supports mainstream AI stack with GPU acceleration. Further more, a dedicated hardware NPU accelerator coming up next for ROCK Pi will boosts complex Machine Learning algorithm and reduce the power
I just set up one of these, to be a controller for an smart TV that can no longer update, and apps like YouTube won't work because it's too old.There are a few things to know.1) This isn't a 4C. It's a "4C Plus" or "4C+". There are a bunch of Rock Pi 4 models, and they don't all take the same firmware. Make sure the one you download is for 4C+ !!! Verify it by looking at the markings on the top of the board, right by the big Rockchip chip. The product picture shows it's "Rock Pi 4C Plus"2) It requires an antenna. Without the antenna, it can receive enough of a signal to see that your access point is present, but it isn't good enough to actually connect to it. I just took mine from a Orange Pi Zero2, since they have the same connector. The antenna connects on the opposite end from the USB ports.3) It's not a desktop computer, but it's close. Set your expectations reasonably, and you'll be pleased with it. If you're watching video with it, don't have a bunch of other apps open at the same time. It will be slow doing some things.4) SD cards are slow. Even the fast ones. It does have a slot for a M.2 NVMe SSD 2230. If you're going to use it a lot, get a SSD and install the OS to that. The same can be said about spinning hard drives on desktop computers. The NVMe will be faster, and you'll appreciate the increased performance.All said, I'm perfectly happy with mine. It meets my reasonable expectations. The only part I didn't know was about the antenna. Don't skip plugging in the antenna.I expect that mine was returned because they couldn't get the WiFi to work. I found a ton of people complaining about the same thing online. It's reasonable to expect a chip antenna or PCB antenna built on, but it isn't. Plug in the antenna.
