Re: GBA SPi-Zero with custom AIO board [Battery Update]

Is the USB port strictly for interfacing the microcontroller or could it also be used as the USB otg on the pi for things like external controllers? It actually doesn't go to the microcontroller at all. The full size USB port is just for connecting to the Pi, for things like keyboards and external ...

Re: [Guide] ili-9341 true 60 fps fast refresh tutorial

I would be very interested in someone confirming that it works well on a PI0W. This is something I would change pinouts on my board to get implemented. But right now I don't have a setup available to test this. Can someone confirm it does work on the PI0W? Is is also flexible like regular fbcp in th...

Re: Looking for GBZ Slide Switch (UK only)

Hi, i'm trying to source a couple of slide switches for a GBZ build (locally in the UK for postage reasons) ideally DC 50V 0.5A 6 Pin 2P2T DPDT PCB Horizontal Slide Switch Side Knob SK22H03 . You could try the UK Digikey website: https://www.digikey.co.uk/products/en/switches/slide-switches/213?k=s...

Re: On-Screen Battery Monitor Options

How much amp can the sparkefun board sustain ? I need something able to get around 7A in his face without crying lol Probably not 7A through the small traces they have on that board...but the nice thing about these maxim battery monitors is they don't actually go in the current path, so they don't ...

Re: On-Screen Battery Monitor Options

Do you use a dev board for that chip? Do you have a link to one? No I just designed it directly into my board. But the sparkfun board could be useful for development. datasheet: https://datasheets.maximintegrated.com/en/ds/MAX17040-MAX17041.pdf on mouser: https://www.mouser.com/ProductDetail/Maxim-...

Re: On-Screen Battery Monitor Options

for me personally im not looking for great accuracy, as long as there is a rough gauge of whats left that will work for me . It will give you a very rough gauge of the remaining battery capacity. But just keep in mind that when your measurement says it's at 50% capacity, it could actually be anywhe...

Re: On-Screen Battery Monitor Options

Not to knock all the hard work everyone here is doing, it's great. But doing straight voltage measurement of a lithium battery with an ADC to try to determine the state of charge of the battery is not very accurate. The voltage curves of lithium batteries makes it hard to actually determine the stat...

Re: Issues With Stereo Audio(Pi3+PAM8403+ Kedei HDMI)

I also got a 50uF cap to put on the power rail. Do you know how this doesn't manage to draw a lot more power? I'm just reasoning that the power and ground rails are sort of being bridged with the cap. I realize tha cap has resistance in it I assume and that it's not bidirectional so I assume it won...
