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...

With a simple small and compact uSD Samsung Evo or SanDisk A1 or similar A1 rated card, the 3B+ is perfectly usable. It'll boot up faster than you can blink. Install Raspbian directly using the Et...

Re: ScriptBasic

From my point of view, I just see you as making it useful on the Pi, for whoever wishes to use it.

One though, if you use WiringPi, does that make it easier to port to Arduino type devices (that's an open question to anyone that knows).
I don't know what its benefits are over pigpio.
