We've sold 25million Pi devices, compare that to the number of SD card issues described here. Hopefully that will guide your decision.

The GPS overlap annotation will use GPS time rather than system time. The standard time annotation uses system time.

Re: Banana PI vs Raspberry PI

Browsers are really terrible with requiring huge amounts of memory (still have no idea why, bad coding I suspect), You could try Firefox, which I believe uses less memory, and there may be other options.

Have no idea about the Banana Pi, I know they ripped off our name a bit.

Re: Pi 3 is Destroying SD Cards

I have had several PIs fail now where the common factor seems to be the SD card getting very hot. as with other posters, I have taken micro-sd cards from known working devices (like cameras) and then had them destroyed by PI 3B+ PCBs. Unlikely. We've had no confirmable reports of this happening, an...

Re: RPi3 Freeze

All right so you are saying that it has to be the "swap partition"' fault. I mean maybe Pi-hole or Deluge installed it automatically. How can I fix it? It doesn't HAVE to be the swap, but we do not recommend swap partitions on the SD carad as it wears them out. And the issues you are seeing could w...

Raspixxx camera software - changes

Hello all, I've recently made quite a few changes to the raspi camera software, but hopefully with very few visiible to end user differences. I've moved a lot of code around to try and make it easier when adding features that they make it in to all the relevent apps without code duplication. In addi...

Re: Raspberry Pi is not connecting to internet via ethernet

This is something that should "just work".

I pressume the Pi is up and running and using Raspbian, so simply plugging in the ethernet cable to the router should automatically negotiate an IP address.

Likely to be something with your physical setup. Can you describe it?

Re: RPi3 Freeze

Nothing obvious in the log that I spotted. You are using a swap file, which is probably unnecessary.

What are you actually running overnight?

What version of Raspbian are you using?

Do you have anything plugged in?

I've just tried this, with a rather old Bluenext GPS dongle, appears on /dev//ttyUSB0, and `cgps -s` works fine. It does take a few minutes after plugging in the dongle for any data to be valid.

The Arduino is also much simpler, and you control all the software that runs on it, whereas in Linux there is probably 1000 times as much software running, almost all of which is code from elsewhere. Now most of that code is pretty good (the kernel), but because there is so much of it, you cannot be...
