This is my first post here on Pimoroni. I’m currently having issues with the third Pi Zero that I’ve been working on as it has stopped powering on. I had originally had power to it after soldering on a set of GPIO connections and connected it to a Unicorn pHat, but when I attempted to power it on by itself it wouldn’t power on. I see no LED illuminating and can no longer power it on when connected to the pHat. This is the same when using a known good power source (tested with a known good unit) and minimum system configurations.
In order to share something that might have caused the fault, I was in the stage of testing it through a HDMI monitor and had a monitor connected, a newly imaged SD card connected and a WiFi dongle connected. When plugging in the power Micro-USB everything went dead.
Any help would be awesome, but I’m worried that I may have inadvertently killed the Pi :(
