cool, thanks
what U think ? external temperature install and testing 
got my esp32 devkitc from china
it seems i am very unlucky this one does not work too
no modules found no testcode work
have tryed new firmware(25) and from other computer
i made a putty screenshot on testcode
That output looks like it is reporting an invalid application image. Perhaps try and erase the flash and try again?
disconnected again from pcb and flashed test code
same putty output - invalid header
i dont know what else to do
this is crazy
have ordered 2 new esp from other seller, this is insane.
Just to be safe, try flashing one of the older releases, just in case a problem has crept into the new build process on GitHub.
where can i get the oldest controller test file for flashing with node mcu flasher?
They are all on GitHub, in the release section
the controller test file is only available since 3-17 release
Hey Stuart, there are lcd touch panel displays available with an sd card slot on them, will that work if I just remove the card slot on the board?
No need to remove the card slot on the board, just don’t use both at the same time
Sorry didn’t realize you were using the test file.
That file cannot be programmed using nodemcu flash tool, the file is not the correct format.
Can you use the real controller code without problem?

2 of my 4 test v4.21 modules are not working,
i tried this with the new arived v4.4 modules and they worked on first try with old and new firmwares
have soldered the attinys exactly the same on 4.4 and 4.21 modules
maybe some bad solder on attiny il check this
