Hi, I have installed Retropie and followed this guide, but I still have some problem. After I type sudo modprobe fbtft_device custom name=fb_ili9341 gpios=reset:25,dc:24,led:18 speed=16000000 bgr=1 the backlight turns on. But when I type con2fbmap 1 1 nothing happens on the screen and the terminal s...

You need to make a little modification to run the screen from 5V. You have to connect the VCC input directly to one leg of the voltage regulator, like this: https://postimg.org/image/cm42j3ryx/ , http://i86.servimg.com/u/f86/18/04/94/98/img_2011.jpg . But it seems like you have a little bit differen...

Hi,
does this work the same with recalbox?

Could I use this circuit but with 4V zener diode?

Hi everyone,
I want to make a simple device, which would light a led when my lipo is charged (input is above 4.1V). It should be as small as possible. Does any of you have some good schematic for this? Thanks.

OK. And could the RPi work if I power it directly from the LiPo?

The battery is charged to 3.8 V, so that shouldn't be a problem. Output is 5.1 V, which is also fine. I don't think there could be problem with connection between the battery and the module, because charging workes fine. The module is connected to the RPi via a USB cable. Couldn't there possibly be...
