JFYI You can use the downloaded file as is with no need to unzip it first. Win32Disk Imager and Etcher can write to the SD card with it as is. Are you sure Win32DiskImager can use the zipped file?

Re: I2S and I2C on GPIO-Pins

I'm no expert but I don't think you can? i2c is a shared bus but I'm pretty sure i2s isn't. I think you'll just get the two devices fighting each other with neither working. If I'm wrong I'm sure somebody will correct me very shortly.

Re: Temperature sensor and real time clock

i2c is a shared bus, you can connect multiple i2c devices as long as no two have the same i2c address. And they all use 3.3v logic. I have one Pi that has a DS3231, BME680, Si1145, Sense Hat and an LED Shim all wired to i2c. The LED Shim is powered with 5V but uses 3.3v logic levels so its fine for ...

Re: Using E Ink as a Raspberry Pi Display?

IMHO, thats not really practicable. The refresh / screen redraw rate is way too slow. Its meant for a static display that can be periodically updated.
Doing what you want to do will likely wear it out prematurely.

Re: Power button (halt/wake) without GPIO3?

Yeah, the Run pin is something like the reset Button on a PC. If its running and you push it, it will do a hard reset / reboot with no proper shutdown in between. Not a good thing.

I do believe he is referring to Pins 5 (GPIO 3) and pin 6 Ground. I just plug a two pin pigtail into those two pins and wire a momentary switch to the end.....

i2c is a shared bus, you can have multiple devices on it. I would think grounding the SCL pin, logic low, to turn the Pi on isn't going to hurt any device connected to it? Using it for shutdown may be another matter, while still using it for i2c? The ground to initiate the shutdown is likely going t...

Re: The Best PI for the job?

I would use a 3B+. It's currently the most powerful Pi with the max amount of available RAM with the current SOC. And it has 4 USB ports.
I quit happily ran KODI on a Pi 2B and then a 3B. No complaints as far as performance goes. I do it all on my XBOX now though.
