  @felmue oh, nice and inexpensive problem solver product. i will use it. For now i have a extra Power Supply for the S3 Device with 12V2A output and set the external Power in UIFlow to Output Mode, but in the Product Page i read on the End it is for Port A and MBus. The MBus is for the Stacked Devices ? But currently there are not many Stackable Modules out that can be used with UIFlow on the S3. And i think Core 2 Modules will not work with the S3 Device when they can´t be added in UIFlow ?

  @ckcampbell248 Update...I think I solved my own problem. I believe the problem is with the Notepad app in the demo firmware. We tried several different SD cards that were known to be working in M5Launcher and they all failed on two Cardputers using the demo firmware. I installed Launcher on my device, and I am able to install .bin files from the SD card.

  Hi there, I would like to use the M5StickC Plus 2 to measure several capacitive sensors in a loop by reading their voltage depending on their charge/discharge curve.
  There are 12 sensors in total so each one needs their own analog pin on the ESP32. The fact that the ESP32-PICO-V3-02 offers 2 ADCs would make it possible to parallelize measurements. Hence 6 of the sensors could be measured on ADC1 and 6 others on ADC2. Would this somehow be possible with the M5StickC Plus 2 ? There are 2 problems that I see with this:

  not enough pins left because of peripherals inside the M5StickC package occupying them

  no way to access the left-over pins other than the GROVE port which can only give me e.g. 6 additional analog Inputs using the PbHUB

  Any help?

  Dear all,
  I am trying this device : https://shop.m5stack.com/products/atomic-speaker-base-ns4168 using the software from this link (https://github.com/m5stack/M5Atom/tree/master/examples/ATOM_BASE/ATOM_SPK/PlayRawPCM)

  This is the message i get when resetting the atom lite :
  ets Jun 8 2016 00:22:57

  rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

  E (89) I2S: i2s_set_pin(314): mclk config failed
  I2S Write

  I know the software is running through some checks in the software i have build in.
  But i do not here any sound. No beep at startup and no soumd when i press the button.
  This function returns a false : _AtomSPK.begin()
  The weird thing is that the definition is : bool ATOMSPK::begin(int __rate) but it is called without __rate defined.
  Within the begin function the error occurs in : err += i2s_set_pin(SPAKER_I2S_NUMBER, &tx_pin_config);

  Any idea?
  Thanks
