Rock Pi 4C Plus RK3399-T Single Board Computer LPDDR4 4GB Support Android 11.0 and Linux

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.

Nice little board to mess around with and the price was nice in comparison to Raspberry Pi's

Ok, so it's my bad for just presuming this case would fit a rockpi 4c, but when I compared circuit board layout it really looked like it should. Well, it does mostly, but the spacing is just a touch off and the heat sinks are just barely the wrong size. You pretty much have to tighten the screws as offset as possible for it to work. I ended up using the bigger heatsink that came with my rockpi 4c board purchased by itself, purchased from the same seller and which is bigger and better...but the ram chip is still exposed and gets hot and there is no heatsink provided for it. The smaller cpu heatsink in the case kit would have worked if it were just slightly smaller. As it is I fear it would short something out. It strikes me as weird that this case came with smaller heatsink than buying the 4c by itself as well.

When I searched for "Rock Pi X case", this case was the first result. I loved it from the start; it matched my Jetson Nano case and I just knew it was the right case for me. I knew the form factor between the Rock Pi A/B was similar to the X, so I figured, why not give it a shot?When the package arrived, I opened it with glee. Finally, after days of waiting, my Rock Pi X would have a home.After spending the first 60 minutes tearing off the paper and successfully poking out three of the four screw holes for the bottom plate that were, unfortunately, still embedded in the acrylic, I quickly mounted the bottom plate to the massive heatsink that came with my X. Well... 3/4 of it, anyway.It was then that I realized my biggest issue: there wasn't a chance on this green Earth that I was ever going to be able to mount the top plate. You see, with the Rock Pi X, the board-sized heatsink attaches directly to the board via the same screw holes that would be used for the mounting posts. Unfortunately, given the included hardware, there was no feasible way to get the top portion of the case attached.In the end I at least have a bottom part of a case whereon I was able to attach 3 of the 4 screws, since the 4th screw hole was clearly etched with a dull butter knife and wouldn't come out to save my life. But hey, the heatsink no longer touches the desk and it's allowed to breathe... So winning?!?

Ain't no way I'm paying that much for a SBC....
