Hi I followed instruction for an installation on a new Pi Zero W (pre-soldered pins) and nothing happens. I’ve read most of the threads here but it seems none had a definitive answer. I also looked over other forums with no luck.
It doesn’t show on i2cdetect -y 1. There is a light lit next to a rainbow mark, only hint that it might work.
Where should I begin to try finding how to make it work?
How do you uninstall the board and drivers, to start again?

The Display Hat Mini uses SPI, not i2c.
Display HAT Mini at Raspberry Pi GPIO Pinout
The light next to the rainbow is the RGB LED. If not set up, and turned off, it will light up at about half brightness. R, G and B gets you white.
What OS is installed, version etc?
Is pip3 install displayhatmini what you ran to install it?
If yes any error messages?
Hi Alpha.
I had problems installing the hat but it t wasn’t the hat, or so I hope.
I was installing the display to a brand new Zero 2 W. The pi seemed to have problems running Chromium. I thought possibly because they don’t have much memory so I was installing everything through SSH. It turned out the Pi is faulty. The SD card socket gets incredibly hot very quickly and it burned the SD card.
The Zero had Bullseye 32 lite with desktop nd a 16 GB Sandisk SD Card.
At the beginning I thought the LED was the cause of the problems. After the board had become totally responsiveness. I turn it of power and separated from the hat. The Zero never turned on again and I thought it was something to do with the hat, that’s it until next day wen it I tried the card in the Pi4 on it. It turns on but the SD card gets iron hot very quickly. Now I have everything stopped until I find out if I can get a working Zero.
Thanks you for your help, 'do.
It sounds like an update / change in Micro Python has mucked things up. I have a Pico Lipo running the current example code OK. I’m thinking if I flash it with the latest uf2 I’ll end up seeing what your seeing. Thanks for posting the solution. 👍
