Docs and Libraries for K016-B (M5Stick Mini Development Kit)

fletli

Dear All,

Does anyone have documentation (schematics, etc.) or libraries for the M5Stick Mini Development Kit K016-B that is not supported anymore? This is the only M5Stick assembled with MPU9250 IMU, and I need this in my current project.

K016-B

I especially need to know the followings:

Wiring of the display driver (SH1107)
Wiring of the MPU9250

Please share any useful info.

Best regards,
Peter

Thank you @felmue!

It helped a lot. Some of the demos are working from here: https://github.com/m5stack/StickWatch/tree/master/demo
Unfortunately, I am still not able to make the display work. This project (https://github.com/m5stack/StickWatch/tree/master/demo/GraphicsTest) compiles but the screen remains black.

I keep trying to figure out what is wrong. The factory test can use the OLED, so the hardware is OK.

Cheers,
Peter

Are you sure it has the MPU as the MPU was an optional extra.
Funny thing is that I'm actually looking at setting one up with mainstream Micropython 1.19

Finally, it is working. Originally I tried it with VSCode and PlatformIO with the latest u8g2 display library, but it dod not work. Then I moved the project to Arduino IDE with u8g2@2.26.14, and it works now!

@ajb2k3, Yes, it has the MPU9250. I ordered the last 3pcs from a local retailer. Now I check other stores too :)

Hello @fletli

I am glad to hear you figured it out and got it working.

What is so special about M5Stick?

Thanks

@fletli I have a video going up soon on how to get it to work in Micropython which turned out very easy in the end.
