Sorry, i have to give up on this. Something strange happened yesterday.
After getting quite bad sound quality out of the node module i did something else and suddenly i heard a bang, followed by a strange smell.
After unplugging and disassembling i found at least one capacitor dead in the module.

Have not decided if i salvage some parts or try to get at least the leds and the IR back into function ... currently it is just heating up when i power it.

I was trying hard to get this working yesterday and used the sample from http://forum.m5stack.com/topic/143/lesson-6-1-speaker-mp3-player/2

Tried to reconfigure the dac output by changing the following according to the information here https://docs.m5stack.com/#/en/base/node_base

out = new AudioOutputI2S(0,0);
//#define I2S_WS 13 //LRCLK - Frame clock
//#define I2S_BCK 5 //BCLK - Bit clock
//#define I2S_IN 2 //DACDAT - Serial data input.
//SetPinout(int bclk, int wclk, int dout)
out->SetPinout(I2S_BCK, I2S_WS, I2S_IN);
out->SetOutputModeMono(true);
mp3 = new AudioGeneratorMP3();
playing = true;
mp3->begin(id3, out);

but no luck -> the file still got played through the internal speaker.
Maybe somebody has a clue how to proceed

Sorry - not yet - i would need some help there - i have the audio libraries in place and the pins should be correct but when playing testsounds i only hear squealing noises :(

Here is some testcode for everybody to get started in Platformio (Arduino)

• Unfortunately i could not get the i2S Dac output to work yet, maybe someone has a clue.

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.

Scanning...
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?

Thanks
Chris

Thanks :D i am aware of that... I was searching for a pinout of this

:D

I saw this video as well - probably i'll try (if i find screens which still have vga ;) )

By the way -> happy new year ( i hope everybody has a nice celebration over there )
Cheers C

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
Chris

@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
