New specs - By Valden

Author :  Valden

The new specs just came out on the kickstarter page !

  • Microcontroller: ATSAMD21, 32bit ARM Cortex M0+, 256KB flash, 32KB RAM, same as Arduino Zero
  • Display: 1.8", 80*64px RGB 16bit (or 160*128px, indexed 16 colors). 25FPS refresh rate by default, up to 50FPS.
  • Battery: LiPo 3.7V 900mAh (to be confirmed), charged through micro USB B port (like a regular phone).
  • Sound : 10bit DAC, mutli-channel 8bit WAV playback, 2.5W class-D audio amp, audio jack 3.5mm, 1W speaker
  • Back lights: 8 independently controllable RGB LEDs for light effects in your palms!
  • Buttons: D-pad, A, B, Home, Menu
  • Backpacks (aka shields): All GPIOs you have on an Arduino Zero are free to use on the back of the console. The developer backpack is compatible with Arduino Shields. Warning: Gamebuino runs at 3.3V, it's not 5V compatible. The DAC output is used for sound. SPI slaves are present on the bus, but won't prevent you from using it.
  • Micro SD card socket: FAT and FAT32 compatible. Optionnal micro SD card with plenty of games provided with the deluxe early bird and deluxe perks. Change between games on the go, not computer required!

I'm so hyped by the new resolution of the console, now we can do games with almost the same resolution as the Gameboy !

For those who don't know, the Gameboy (and Gameboy Color) have a screen resolution of 160x144 pixels, making the new gamebuino 16 pixels smaller in height.


That is still way larger than other consoles!

Arduboy: 128x64

Original Gamebuino: 84x48

What? Where is the 4k? ;)
Size is great in my opinion. A good balance between processor power and pixels it has to push IMHO.

What? Where is the 4k? ;)

Use the pins to connect a 4k screen? :P

Oh this is using the same µC so should be easy to use in the Arduino IDE

Author :  Sorunome

You are able to program the META via the Arduino IDE......what else would be the point in making it arduino-compatible? ;)

Author :  ripper121

Yes sure but good that it based an a pices which already exist. Than also there are already some useful examples and libs.

Will the speaker be louder than my
latest gamebuino original?

Author :  Aurélien Rodot

Sound on the META is way, way above the Gamebuino Classic. You can even feel the sound vibrations with your hands.

Author :  erico

Exactly like Rodot said, on my gamebuino meta prototype the sound is quite loud and very clear.

Author :  Valden

Nice ! Can't wait to compose some chiptune for the Gamebuino now ! (can we get a sneak peek of the Pattern song format for the Gamebuino Meta ? :3 )

Author :  MicroGames

"low volume"

Yeah, I know poor quality

Author :  Aurélien Rodot

It plays WAV (44Khz 8-bit mono uncompressed) so you're free to compose on your favorite tools and export to WAV :)

Author :  erico

Something like .mod or .it would be really cool, specially the later.

Author :  Valden

.waw playback is really cool, but it's also kinda heavy (but I assume we will put them on the SD card, so it's isn't as much of an issue).


Author :  Sorunome

Yeah, wavs are played back from the SD card.


We only have 256k of flash which would translate to only a few seconds of audio ;)

Will the new gamebuino load games the same way as the old one? Because I am worried that when You will load/exit a game 10,000 times Your gamebuino will stop working because this is the number of flash rewrite cycles in the atmega 328p.

Author :  Sorunome

There isn't really anything to worry about.

Let's say you switch games on average 8 times a day, as you go via the loader that'd make 16 re-flashes per day.

That would mean the flash would last 625 days, or 1.7 years. Now, that is short, right? Agreed. Keep in mind you won't be using your gamebuino every day, so let's say you use it for half the year, now you are suddenly already at 3.4 years. Still low.

Now, let's look into what the write limit really is: it turns out, flash companies usually say 10k flash cycles only to be on the safe side, but it is very normal for a flash chip to have more than 100k flash cycles. Now we are at 34 years of continuus gamebuino use!

Now, on top of that flash chips are also larger than specified and automatically swap out bad cells and thelike....


Think about it this way: every time you copy a file onto a USB-stick, are you worried of breaking the USB sticks flash memory because of writing too much?

What display does this use? I know the resolution but ... tft? Can we get more technical info on the display? :)

Next time use the search function!
