unfortunately the power button broke of my M5 (of the pcb) when pressing it on.
Tried to repair this but I failed. Anybody here with the same problem.
Currently uploads do not work. How can I fix it
Is there a excact list available of parts e.g. were to get a replacement items like micro switch or other parts like the display.

Hi Chris, haven't seen any other reports of this..... I've used quite a few M5's without any button problems.
Some parts are referenced on the last page of the info sheet included with the M5 - but not the buttons. Don't think there is another list referencing parts.
In terms of a fix:
Presumably the M5 powers on when connected to USB. So I'm assuming you sometimes need the on/off/reset button to operate as the reset button when you are uploading code. And naturally you need the button to power on the M5 when dis-connected from USB. Is that right?
Connecting a capacitor between the RST and GND ports should solve both these problems. Connect negative to ground , positive to RST.
When NOT connected to USB, connecting the cap should power it up (can remove cap once started**). Also when uploading code, leaving it connected should allow code to load - or if use of the reset button is needed when uploading, just disconnect and re-connect the cap. Or - connect a button along with the cap.
The cap I use is a 22 uf through-hole cap with polarity. 10 uf max has been suggested as the ideal max - but I've had no problems.
Further discussion re. which cap to use:
** Turning it off could still be a problem.
