    • Use of the M5 Stack logo in projects

      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.

    • M5 Stick C Plus: Sat Nav & Telemetry Console for Scuba Divers

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

    • RE: M5 Stick C Plus 5V HAT output

      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...

    • RE: M5 Stick C Plus 5V HAT output

      I've given up on this, now powering it direct from USB instead of HAT.

    • RE: Factory Test and Microphone example not compiling M5 Stick C Plus (latest version)

      @bazman Fix is to delete the line! Both the microphone example and the factory test project then work.

    • M5 Stick C Manual found - where is English Version?

      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?

      https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/M5StickC_Guide.pdf

      Thanks

    • What is spec of M5 Stick C-Plus IR Transmitter?

      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!

    • M5 Stick C Plus 5V HAT output

      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?
