Re: Regarding the current measurement

There are devices like this, https://www.adafruit.com/product/2690 To measure total current drawn by the Pi. Might be a bit of a PITA getting the adapters for it though.

Re: Regarding the current measurement

Wouldn't a round about way to do it be monitoring the CPU load?

Re: Problem: RPi Zero and keyboard

I have a CanaKit branded Mini Wireless that I believe is a Rii, or Rii clone maybe. Model CK.KB-101. I haven't tried it in Buster yet but it works fine in Jessie and Stretch with its included dongle. One advantage to the Logitech Unifying dongle is as far as the PC is concerned, its just a USB HID d...

Re: Problem: RPi Zero and keyboard

Does that dongle / keyboard work OK on a PC? I've used various supplies with my Zero's without issues. 2A, 2.5A. Some were 5V and some were 5.1V. These days I just buy the official power supply and be done with it. Especially if its a 3B or 4B. One less thing to worry about or wonder about. That bei...

Re: Problem: RPi Zero and keyboard

One thing I have noticed with a Zero is if its booted up, and you swap or plug something into the USB DATA port it has a habit of rebooting. That seems to be a problem with the newer models. There must have been some hardware change that was not accompanied by a revision change (same v1.1 revision ...

You only need the standoffs if your doing the original stock install where the Pi is mounted to the back of the display right on top of the display driver card. Just attach the driver board with the screws that would normally be used to attach the Pi to the stand offs. And put the stand offs away fo...

Of more interest would be the fact that Raspbian does not appear in that list at all!
I see a "View 3+ more" option so maybe its just hidden. Still, you'd think it would be first, or close to it, in line.

USB C for the touch only, or USB C for touch and display?

Windows 10 IoT will run on a raspberry Pi. It bears no resemblance to the Desktop Version of Windows 10 though.

I have two of the old A+'s running here with sense hats attached. Both have RTC's attached and don't need wifi etc. They are setup as weather clocks displaying local real time conditions. One runs on battery at times so the A+ is great for that. The Zero was not around when I built them.

Pimoroni limit themselves to the top model of each model type A B etc. Zero, Zero W, 3A+, 4B. They have always done it that way. I buy a lot of stuff from them.

Re: Power multiple Raspberry Pi 4 B

Just FYI, you don't have to power the Pi 4B via the Micro USB port. You could feed power in via the GPIO +5V and ground pins. There is no real need to feed power to the Pi 4, or any Pi, from a USB port. On some older models this will bypass the poly fuse, so just keep that in mind. If your making up...
