Are we permitted to use the M5 Stack logo in our projects? I mean specifically as a label on the outside of the product like I have done for Blue Robotics in the hackaday project linked below and in the photo attached. The logos showcase the technologies used in the product.
I am using not one, not two but three M5 Stick C Plus cores in this project! I want everyone to know that it's powered by M5.

Please check out and follow my new project on hackaday. It uses not 1, not 2 but 3 x M5 Stick C Plus cores!
Thank you so much!

Thanks @teastain. Is there an API to tell what the 5V In voltage is from the HAT? I use the USB voltage to work out if the power has been cut so that I can automatically shutdown the device instead of using battery power. I wonder if this can also be done through the HAT power in...
I've given up on this, now powering it direct from USB instead of HAT.
@bazman Fix is to delete the line! Both the microphone example and the factory test project then work.
Line 438 in M5StickCPlus\examples\FactoryTest.ino and line 55 M5StickCPlus\examples\Micophone.ino has a compile error on the line marked ----> below
i2s_pin_config_t pin_config;
#if (ESP_IDF_VERSION > ESP_IDF_VERSION_VAL(4, 3, 0))
--------> pin_config.mck_io_num = I2S_PIN_NO_CHANGE;
#endif
pin_config.bck_io_num = I2S_PIN_NO_CHANGE;
The error is:

This is in Chinese for M5 Stick C. Does anyone have a URL or the PDF for the english version of this document and for the M5 Stick C Plus English manual equivalent?

I want to build a receiver of Infra-Red to detect transmission of IR from M5 Stick.
What is the transmitter diode used in the unit? I need to know the frequency response and the infra-red band that is transmitted.
The best info would be the actual manufacturer and part number in the M5 stick.
Thanks!
The M5StickC-Plus is being powered through USB.
The grove port is in use, connected to a temp/humidity sensor (Adafruit AHT20) and magnetometer/accelerometer sensor (Adafruit LSW303AGR).
I am connecting an RS485 board (using a MAX485 IC) to the HAT pins, but the 5V output is only at 1V.
Any ideas? Does the 5V output have to be enabled in code?
