Re: Dead after 5.5V Input at micro USB

He says that one cannot simply “solder” PMIC without special devices - for example, without a special device for heating the entire board. “Balloons will float” under the processor or the board will be twisted by a screw. That's exactly what he says. So it is better to immediately forget about the ...

Re: Raspberry Pi4 Boot Partition

We currently recommend etcher because its easy to use, multiplatform, doesn't require you to unzip the file, and works in almost all cases. There are some cases where it apparently doesn't work, although I've never seen one. Jamesh also agrees that in some cases it doesn't. I have seen many cases a...

Thank you for the information.

Both Etcher and Win32DiskImager write a bit image file to the SD card, just like DD does in linux. This is at the bit or sector level, so effectively they format the SD card and write the data at the same time. They have no real knowledge of the file system or the data inside the image. None of the...

Re: Please check Official Link.

The Raspberry Pi's bootloader, built into the GPU and non-updateable, only has support for reading from FAT filesystems (both FAT16 and FAT32), and is unable to boot from an exFAT filesystem. So if you want to use NOOBS on a card that is 64GB or larger, you need to reformat it as FAT32 first before...

Wrong. Please don't post any more incorrect and unhelpful information. According to the SD specifications, any SD card larger than 32GB is an SDXC card and has to be formatted with the exFAT filesystem. This means the official SD Formatter tool will always format cards that are 64GB or larger as ex...

Re: Raspberry Pi4 Boot Partition

There's no need to format the SD card before writing the image to it. Writing the image replaces everything on the SD card including the partition table and any formatting already done to it.

Use Win32DiskImager

Hello there Friend, I don't suggest etcher as I have found many people are facing such issues. I suggest you using Win32DiskImager. Simply just download the iso image and write it to the sd card. And once you are done with that you can follow this post on how to connect it to your android or Laptop ...

Buck converter

Hello Allen, You can use a Lipo battery of higher mAh(10000 mAh) just you will need to put a step-down converter(buck converter) with 3A max output. And it should give 5V DC 3A output constant and it will work fine with your raspberry pi zero. The above will be suitable for your application. :ugeek:

TV pictures were therefore given a black border so that none of the pictures were lost; this is called overscan. Modern TVs and monitors don't need the border...
