Re: Pi Zero - WiFi Hardware Missing

Did the PiZeroW WiFi still work with the two white bits missing, surprisingly my Pi3B with the old ceramic antenna still have reasonable Wifi with it missing (I have two fallen of now) Much prefer the new design.

Only SATA port is missing.
for good reasons, no room, little use to most people, you can use USB3 anyway to do the job.

Re: V3D/VC4 detection and legacy driver.

6by9 : You'll have both "v3d" and "vc4" loaded. Thanks, it should work as it is then, since I already detect "vc4" (but I might add "v3d" too for future-proofing it, just in case in the future vc4 won't be needed any more on the Pi4). jamesh : You should be able to run both the Pi3 and Pi4 in eithe...

Re: Raspberry Pi 4 Thread - general discussion

As the WiFi is just a module, I assume it is still fine for RS/Farnell to have orders for customised Pi4 without the WiFi/BT module there.

So perhaps the person needing it can order a lot of them and then resell them and fill that market they can see?.

Re: Is my cell phone charger good enough to supply power to my raspberry pi

RPis with the BCM2835 and BCM2836 SoC may be powered by some (not all) reputable phone charger as long as it's rated capacity complies with the board requirements. The BCM2837 and BCM2837B0 ones are more power hungry, and phone chargers cannot keep up with the requirements of the board. Remember, p...

Re: Is my cell phone charger good enough to supply power to my raspberry pi

Does it use a separate 'usb' cable as the power wire? Or is is a proper all in one like the Official Pi PSU. I would try better USB 'power/charge only' leads if you can find them. There are some rated for 2.5A delivery. The cable and the uUSB connection itself create the largest voltage drop from my...
