Hackaday.io member Moosepr Has published a new project which uses the awesome and incredibly small Raspberry Pi Zero mini PC to create a super small GameBoy Zero, which could be the smallest GameBoy Zero made to date.
Check out the video below to learn more about the build which uses a ili9341 screen, a Pi zero, 2 navi switches (5 way), and a battery.
Its creator explains a little more about the project which can be seen in full over on the[Hackaday.io] website by following the link below.
So the pi zero is cool, retro gaming is cool, im really not cool, but i thought ‘what the hell!!’ Im not overly fond of ‘rats nest’ wires, and i have a bit of an obsession with making things as small as possible, so this is what i came up with.
tis just an ili9341 screen, a pi zero, 2 navi switches (5 way), and a battery (with charge/protect circuit)
using the notro’s fbtft driver, tasanakorn’s fbcp code to get the screen to display, and adafruit’s retrogame code to work the buttons
The eagle eyed among you might spot there is no ‘boost’ circuit!!! The pi zero is actually quite tolerant, you dont actually need to feed it the full 5v to make it work. The main core of the pi runs on lower voltages, so the majority of it will happily run as low as 3v (i have heard it will run lower, but li-po protection kicks in before we get there), the only real need for the 5v on the pi is USB peripherals, which most will be ok with 3v too!! Therefore the battery (4.2v-3v) is piped straight into the 5v line on the pi, cutting a boost circuit out of the mix, keeping the power usage below 250mah
