the new controller has four on-board relays, two blue ones (top left area of your PCB pic) which have three screw terminals (NC, COM, NO) and then there are two smaller black ones on the bottom left side of the PCB picture that are like a traditional switch (open or closed circuit).
You would need to add a number of jumpers to use the existing relay board on the new controller likely. It would likely be easier to extend the relay wires to the new controller board instead.
There is only 1 led now, it’s blue because it’s cheaper than green from jlcpcb!!
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
