Thanks for your replies, i tried the proposed arduino example and unfortunately got the same results - no response from the bmm.
I will contact the shop
have a nice day

I got my recent order today and instantly tested all components.
Unfortunately there is one issue in the ENV hat for the M5StickC.
The DHT12 sensor is working as well as the BMP280 but the bmm15 is not showing up.
A scan of the i2c bus shows that the device is not present at all.
I2C device found at address 0x5C ! (this is the dht12)
I2C device found at address 0x76 ! (this is the bmp280)
Found total 2 devices
Does anyone else have this issue and probably a solution before I contact the store for an itemreplace?
Unfortunately my tft cable got ripped off the pcb when i disassembled the m5stack (because i was nosey how my m5Stack is looking under the hood.
Currently I am using the damaged unit for another project where i don't want to have a display but all the other features.
I could not find any description or pinout for the display itself but would like to use it.
Can anybody please provide me a pinout diagram of the connector cable?
Thanks a lot
@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
It's definitely cooked :D I just do not understand what happened and don't want anybody to have a dead esp as well :D
Yesterday I got a nice package from m5 with my awaited Stepper and Servo modules which I need both for a project.
My first test was the Stepper-Module (with original power adapter) on a Fire and the provided test sketch.
It worked perfectly.
My Second Test was adding the Servo module as well and i combined Stepper and Servo test sketch.
It worked as well.
After combining the two sketches ,stacking Stepper and Servo board and connecting power nothing happened.
While disconnecting and disassembling again to check what could have gone wrong i burned my thumb on the really hot esp32 cover.
So obviously something has gone terribly wrong.
It seems that the fire is dead now and if i connect it to usb it gets hot again and does not do anything.
Probably somebody from m5 can check this - i don't want anybody else to have the same issue with a killed M5 Fire
That sounds perfect - yes i have an usb isp :D
Just a sneak preview of the animatronic robot (this is a "just for fun" project ...)
I just saw the new M5Stack New SERVO Module 12 Channels on aliexpress and i would like to use it for an animatronic project but have more than 12 Servos.
Does anyone have experience with the module yet and can tell me if the i2c Adress is changeable?
The Stacking option of the M5 helps me a lot getting the necessary hardware ready but if i am limited to 12 Servos i am stuck.
