Re: Supported DPI Output Resolutions

You're using a DPI-->VGA adapter? I've confirmed at least 1024x600 is possible over RPi DPI, at least when connecting directly to an LCD over a TTL parallel RGB connector (EJ070NA-01J and compatibles). I've seen DPI-to-VGA adapters that promise 1366x768 support, I'm fairly certain you won't get a lo...

Re: U-Geek CM3L IO board

Received the boards today. They look perfectly fine and came well packaged in those zip-type antistatic bags with packaging foam on every side. I haven't done any tests yet, just plugged in a lithium battery which seemed to charge up fine -- I haven't figured the power switch out yet, it's independe...

They do some nice cases for raspberry pi's also IIRC
They have some cases with pushbuttons and small LCD screens for diy media players and stuff. They also seem to have machinery/competence to do some pretty good aluminium work,

Re: U-Geek CM3L IO board

I can't find any dimensions in the descriptions, but this entirely scientific and exact measurement strategy of mine gives the board dimensions as 56.9x82.9. https://imgur.com/zhnObZS.jpg Edit: That puts it really close to the rpi 3 dimensions (85x56mm). The HDMI and power connectors seem to line up...

U-Geek CM3L IO board

I found a pretty interesting IO board from a Chinese company called U-Geek; https://imgur.com/BkX45CU.jpg https://imgur.com/xgE9oYT.jpg The only place I found it for sale is on its Aliexpress site , and it has some limited information available on Sourceforge . The board breaks out the IOs in standa...

(Not sure about the legendary bit though)
That was the joke :)

The Pi, great piece of hardware though it is, isn't exactly competing for the top position at CPUboss. This board combines all its weak points with none of its advantages.

Re: ArduCAM with Broadcom BCM2835 SoC

Allwinner have created Linux drivers for many of their hardware blocks and therefore they have taken on the support burden of that. I doubt HardKernel or other of the SBC manufacturers using Allwinner chips have had to do any significant development effort beyond board bringup. Hardkernel doesn't d...
