OSHW: Small tablet based on RK3568 and AMOLED screen
- thenthenthen 11mo agoJust found this Chinese Open Source HardWare site and wanted to share this cute project with you.
- VerifiedReports 11mo agoWhat about it? The site's in Chinese.

- VerifiedReports 11mo agoThis looks like the perfect thing to replace my POS Jenn-Air oven's defective touchscreen control panel...

- sciencesama 11mo ago21 usd
- chvid 11mo agoThat is an incredible price.
- karlkloss 11mo agoAdd transport, tariffs and vat, and you could as well buy a cheap Android tablet from Walmart.
- SahAssar 11mo agoDo you know of a cheap android tablet with a ~4" screen? Cause I don't see those too often.
- zamadatix 11mo agoIt's like trying to find a bus with 4 seats - it won't usually be called a tablet if it's so small (usually ~7" is the cutover).
- SahAssar 11mo agoRegardless of what you call it, can you find a cheap device similar to the the one described in the article?
- zamadatix 11mo agoTo me yes, absolutely. In the page's comments, the listed build costs are described as being based on minimal second hand parts costs. One could skip this step and go for used Android phones directly snugly at the same price range for equal or better features/functionality/performance. The hardest part is to sort through ones which have unlockable bootloaders and the like. Of course there is nothing wrong with wanting to hack on hardware, quite the opposite, just it's not leading to a hardware assembly at jaw dropping prices (even if you consider the used part sourcing/shipping and assembly effort 100% free). To others, it depends what "it" in the page even is to them. I'm sure someone would say "but I want to find exactly a 3.92 inch 1080x1240 resolution AMOLED touch screen with... as seen here - can you point me to that?" to which I'm not sure the price even matters anymore. The only thing that is 100% this device BOM is this device BOM, for however much that's supposed to be worth saying.
- j16sdiz 11mo agoThe comment section say they were using second hand component. Basically salvage yard parts.
- j16sdiz 11mo agoalso, they were taking advantage of free sampling of JLCPCB in China. The main pcb is basically free
- gorgoiler 11mo agoThe right device at the right time can spur all kinds of revolutions. Sous vide water bath cooking was based on a laboratory immersion heaters, the WRT54g router spawned OpenWRT et al., commodity arc welders became a key part of carbon 60 research, XBox Kinect sensors got repurposed for all sorts of proximity hacks. The recent fad for particular brands of child oriented power banks in the through hiking community is the most recent one I can think of. So therefore it’s a long shot, but this device or a device like it could be the mutation that causes a Cambrian explosion in mobile hardware, albeit one where you ahen apparently need to glue the screen on yourself, post delivery. (See the below-fold video.) I cross every one of my fingers!
- nine_k 11mo agoNow it needs a 4G / 5G modem, and a camera, and it could be a compact phone,
- redundantly 11mo ago> The recent fad for particular brands of child oriented power banks in the through hiking community is the most recent one I can think of. This sounds interesting. Can you elaborate?
- throwaway89201 11mo agoIt doesn't fit into the list as a revolution (or even 'evolution') as it's just a high-density, compact and cheap battery [1] that turns out to be quite unsafe [2].

- sho_hn 11mo agoIt's probably a reference to the Haribo power bank thing (which appears to be poorly made and dangerous).
- gorgoiler 11mo agoThrough a chance piece of design, the leading power pack in terms of energy density is made by / branded on behalf of Haribo, a confectionary company: https://www.ultralightnerd.com/index.php/2025/06/26/haribo-mini-power-bank-review-the-lightest-20000-mah-battery-in-the-world/ https://www.ultralightnerd.com/index.php/2025/06/26/haribo-m... What’s interesting is, like the other products, it was designed and marketed for one purpose but has become very popular for another. (Although in this case it could well just be a fashion, especially given how uniquely identifiable the product is.)
- wronglebowski 11mo agoThe RK3568 is an interesting choice, why no the H700 or something with a good amount of mainline kernel support already?
- plipt 11mo agoSite says it runs Linux Does anyone have insights on how compatible that hardware might be? Or how it might compare to something like a Pinetab? For some years I have been looking for a low cost tablet with good Linux support for use in home automation or information displays. Surprised there is still nothing like this in the Raspberry Pi ecosystem.
- deleted 11mo ago[deleted]
- NewJazz 11mo agoPinetab 2 is the very similar rk3566 chip, so support would be somewhat similar (probably a lityle worse, since the device trees haven't had as much attention).
- tty456 11mo agoHow does one get a board like this one made?
- tuetuopay 11mo agoSend it to JLCPCB + JLCSMT. The board was made with EasyEDAY (JLC's web PCB tool) which has a one-click "manufacture" button.
- tuetuopay 11mo agoWhat I find most impressive is the design was made using EasyEDA, JLC's web PCB design tool, and only on a four layer board. That BGA with DDR4 on 4 layers is something!
- ACCount37 11mo agoWhy people actually use those clunky web-based tools is beyond me. It's like using a normal design tool but worse in every conceivable way.
- Renaud 11mo agoIs it though? EasyEDA is more than sufficient for most uses that don’t require large amounts of layers or components. It’s easy to pickup by a novice, has basic ERC, well integrated into LCSC ecosystem. It doesn’t have the versatility of KiCAD but is lighter and easier for light use or occasional design of moderate complexity.
- dsvf 11mo agoI keep wanting to get into Kicad, and the learning curve did become easier in the last years. But what I _want_ is to get a usable board into my hands, not just create a beautiful layout file. Historically, my pain points were were footprints, parts sourcing and SMT soldering. From a hobbyist-with-limited-time perspective, EasyEDA and the integrated JLCPCB assembly flow solved all these problems good enough that the hurdle to figure out how to do it with KiCAD was always higher. The minute I find a similar level of convenience in KiCAD + plugins, I'll gladly ditch being tied to online.
- IgorPartola 11mo agoI tried to start with KiCAD so many times and never could fully figure out how to do the basics of what I wanted to do. Mind you I was designing absolutely basic boards using capacitors, MOSFETs, resistors, some basic SMD sensors and ESP8266 modules. EasyEDA has a downloadable version that is significantly less clunky and the UI makes a lot of sense to an amateur. Plus of all the things I had tried it had me spend the least time finding footprints for components that were actually available and affordable. Nothing quite like picking out a capacitor just to find out that it costs $0.84/each while an equivalent but slightly different one would be $0.0037/each.
