Around 2.5 to 3 hours or so... I am using a 2500 mAh battery.

Very nice :) Do you have a link for that USB hub at all? I found a few different ones that could have matched the title you put in your parts list, it looks like an ideal board :) - Thanks!

Hello everyone, First of all I would like to say a big thank you to the community and to Wermy, I came across the Game Boy Zero build while doing an internet search. I was instantly hooked as I am sure most of you were also. After spending copious amounts of money on everything I needed.. I have fin...

I bought this board thinking it would make a gbz build easier and its made it a nightmare. All hooked up to the pi and nothing. Ive looked for 3months and tried all i can. Gutted its come to a halt. You can certainly use the i2c bus on the Pi... but you will have to write some code on the pi to tra...

The program above is for an Arduino (in my case a Teensy 3.2) where the pcb is connected via i2c (cuts down on the wiring). I don't see why you couldn't use the Raspberry pi i2c bus also... you would have to write a daemon that ran on the pi to convert the i2c data into keyboard commands... it's cer...

If you are looking for some code for the i2c controller PCB... I wrote a program for a Teensy 3.2 that takes the i2c input and generates a keyboard HID output via the teensy usb port. It's a work in progress so I have to tweak some things... I have put it out here to help anyone else who is trying t...

Does anyone know what the I2c connection is for on the 640x480 display?

Change cpu0 to mmc0 to use the SD card to trigger the LED instead of the CPU.

Take a look at Device Tree Overlays, you can assign the ext_act (activity led) to any GPIO.

ext_act_led: act {
label = "ext_act";
linux,default-trigger = "mmc";
gpios = <&gpio 19 0>;

Mono works fine with 3 pins. If you use PWM, put the pot after the filter and before the amp. If you use USB, put the pot after the usb and before the amp (if you used one). Simply take a multimeter: 1. turn the knob all the way to one side 2. check resistance on pin 1 and 2. 3. turn knob all the w...
