I just finished assembling a heatermeter 4.3 with Raspberry Pi Zero W.
I have checked and double checked my solder connections and everything seems to be fine.
When I power up the heatermeter:
The top line of the LCD display in solid boxes.
The Raspberry Pi LCD flashes green rapidly for a short period of time and then goes dark
The Newhaven LCD is the same with or without the Raspberry Pi installed.
I have tried to reflash the memory card several times with the same results. Both the stable release and the snapshot.
Any further thoughts? I don't have a mini hdmi cable handy at the moment but will pick one up later today to try and watch the Pi boot sequence
