Hello,

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.

Hello,

does someone know the manufacturers and the part numbers for the sockets and headers? I read that they may be from samtec, but I did not find sockets with a 2.54mm pitch and 2.2mm profile(height)

Could someone tell me where to get theme.

Thanks a lot.

Hello,

if someone is interested, I did a FreeCAD Model, there is a table with parameters so you will be able to modify the height easily:

I also published the measurements and the stl,... :

Have fun, I hope we can get some awesome modules available on ebay,.. .

Hello,

I found some pictures on the web, the pads are not populated and yes it is a short!! I removed the short with some fluxed solderwick and hope nothing is damaged by the short.

Hopefully the M5Stack-team respondes on how that could happen in production and releases the schematics and placement of parts.

Something else that is really odd, on the Keypad there is no bypass capacitor for the Atmel Microcontroller!

I removed the battery, the pad's are shorted out, can anyone tell me if that is normal? Maybe someone can send me a picture of his unit? I guess I got a bad one, so how can I fix it, is there a schematic?

Thank you very much.

Hello,

I just received my M5Stack with the faces. What I noticed, after I took it apart and reassembled it, the IP5306 was getting hot and even after shutting it off, it staid hot. I also noticed there may be a capacitor missing, not sure, looks odd, hand soldered,... .

I disconnected the battery and took a photo. Can anyone tell me how to solve the problem, maybe where I can find that schematics and if a cap is missing, or latch-up is a problem with the IP5306? Did something latched up is you stack the modules without disconnecting the battery?

Thanks a lot,
