I highly doubt that, all M5Stack likes to do is:
1. Buy overpriced connectors
2. Limit the “openness” and control the marked of modules
I love the idea and package of the M5Stack, but the connectors are just stupid, require high forces, difficult to find, … .
Maybe I will use other very common low-profile types, do it in FreeCAD, and KiCAD so we can get rid of that nonsense connectors for 3rd Party and custom modules.

I get what you mean, it makes a lot of sense. The one you get is surly the soldering mistake , because they didn't put enough tin on the soldering pad. We definitely could do something to improve structures deign just like what you come up with, but its not gonna help that much if we have the bad soldering.
@b1063n said in External Power - What is possible?:
So, did anyone find a solution. I was about to buy it, but then when I look at the documentation for the power supply voltage I cannot find it! Documentation is quite poor I must add.
I do not need battery operated solution, and the USB power is super ugly and inconvenient!
I need to use external 5V power supply connected to pins inside the board in a professional manner (no pcb hacking). Is this not possible? I cannot believe it!!
Yes it is possible as the Stackable modules provide internal power to M5Stack cores. (Sorry been working on my books and documenting units with demos this weekend.)
The documents I have, show that each stackable module has its own voltage regulator that delivers 5 volts to pin 28 of the internal bus (+5V).
If you look at the Proto module you will see that these pins are marked ready for you.
Here is an example (Korean but you can using code, Simple Chat Server)
And I will publish this document in English as soon as possible. :D
I had the same problem. But I did decide to rename all my APs and every device connected. 30 minutes later, still can't get a device code, and it seems like it got stuck booting into the "Press next for instructions" screen, so I can't change the wifi if I wanted to :(
@heybin I’m sorry, I don’t understand why when you have it working for the stick and the stack. Looks like it’s time for M5Stack to build a UIFLOW port of the firmware for the camera. If you build it from the sicks firmware then half the work is done for you!
@mrtarantl said in Pinout of TFT display:
Thanks :D i am aware of that... I was searching for a pinout of this
The contacts are not damaged, it should be easy to solder it again on the board and it will probably work again...
Of course, if you have minimal soldering skills...
@ajb2k3 yes I did use the cooling module as well.
My thought was that there probably is some electrical interference when using the stepper and the servo module together. My solution in that case will be that i disconnect the mbus from the voltage regulator +wire completely to only power the steppers with the external power supply and do the rest with usb power to the m5Stack, so i am safe :D
Have the ezTimeLog example loaded up. It is printing lines at the bottom of the canvas, and shifting previously printed lines up, indeed just like a terminal screen watching serial output. I think I misunderstood the scrolling functionality as the ability to use buttons to go back through the history at the top that had already scrolled off the screen. I see in issue #24 you say "canvas.print creates a buffer in memory that stores every print until it has scrolled off the screen", so that's not the way it works - sorry for my confusion.
Indeed, creating menu items that don't do anything would be a possible solution. I tried that early on, but found that once the menu was drawn (or run), it merely sits and waits for buttons. I have not tried creating a function that does an .addItem, then runs the menu again, and run that function with an .addEvent. I'll give that a try as soon as possible. Is there a limit to the number of menu items, other than memory constraints? If I'm successful getting the "menu" to redraw, I'll let you know, and I guess I'll see what the limits might be!
Thanks so much, @rop, your work is very appreciated!!!
