New RetroStone SBC gaming handheld

Post by sgtgrumbles » Sat May 18, 2019 8:11 am

The RetroStone folks have put a new Kickstarter up for a "metal edition" gaming handheld. Check it out:

It appears to use a custom PCB with an Allwinner H3 (Cortex A7 quad-core, HDMI, 4 USB, Ethernet, audio jack, volume wheel)

I'm happy to see they got the D-pad PCB contacts right! Finally, an AIO SBC handheld with good diagonal inputs :) Notice they're using the old NES/SNES/Genesis style contacts for the D-pad buttons in contrast to the contacts for the A/B/X/Y buttons.

I'm curious about the choice of an Allwinner H3 SOC. I was under the impression this chip didn't support DPI/RBG but one of the pictures clearly states "AV->RGB24". I guess I've been mistaken?

In any case, this looks nice! Goodluck to RetroStone

I hope they are not taking Composite video signal and converting it to RGB for the LCD. It looks a little blurry and Composite video like in the image above. I don't know why they don;t take HDMI output and convert it to RGB and there are high quality chips from TI (if I remember correctly) that can do this.

Retro PSU, 3.5A output!

Don't contact me about obtaining my board files (as you will not get them). Don't contact me about any of my boards if they are sold out, they will be restocked as soon as I can get them.


Don't support thieves like ckliang who copied my AIO to resell and is now cloning the mintyPi, support the original creators and not the thieves!

So this is their Retrostone 1 in a aluminum case. Your hunch is correct. The creator is in the process of creating a version 2 with a better display... I guess some people seemed interested in an aluminum case for the version 1?

The Kickstarter campaign of the original RetroStone has the same picture with "AV->RGB24". I think the only difference is the aluminium case and the lack of the EnergySquare pins.

I have one of the first RetroStrones with the plastic case and the display is horrible. It's 320x240 pixels, fed with an analog signal converted back to digital. It looks like an old TV with blurred lines and poor colors. Cannot recommend buying it. But it looks like they are working on RetroStone 2, hopefully with a fully digitally fed display.

I have one of these and my only complaint is the analog screen looks terrible compared to a TFT.

Other than that it's my go-to handheld, I've been using it for my first Majora's Mask playthrough. Battery life is over four hours and the controls feel good in my gormy hands.
