M5Camera schematic "Pixel Data Bit 4" and "Pixel Data Bit 7" is IO39. Probabry, this is mistake. https://github.com/m5stack/M5-Schematic/blob/master/Units/m5camera/hardware_diff_with_ESP32CAM_M5Camera.md

Thanks gay!

Pixel Data Bit 4 -> IO39
Pixel Data Bit 7-> IO19

I have modified it.

Hi Watson&Sio-funmatsu,

I bought 2 pcs M5cameraX/F from your sale channel and will use it for second develop in IoT domain, i saw the M5cameraX/F schematic is fragmentary, and it is not helpful us to deep use it, any possible you can share the complete M5cameraX/F schematic to me? thanks your help in advance! Andy

Sorry, We can't provide complete schematic document now. What do you want to know? Please tell us in concrete terms.

andywang2039 commented 5 years ago

@sio-funmatsu thanks your reply, i have two question about your schematic.

  1. schematic showed 2 pc LED, one is red and another is blue. but actual sample only has 1 pc red LED.
  2. schematic showed is USB_Micro, but actual sample mounted is type-c if possible, please help provide these two segment clear schematic for me study.

thanks

@andywang2039

I answer your questions. Both questions are our mistakes.

  1. There is only one LED on M5Camera F / X.
  2. Micro_USB is wrong → USB Type-C is correct.

so sorry...and thank you for your advice.

@sio-funmatsu Thanks your answer. I contacted your colleague in parallel who is in China , but she tell me the schematic should be depend on your side and unavailable now. More questions ;

  1. Our end application request USB type is Micro_USB,if we insist use Micro_USB, then any preformation impact for M5cameraX/F?
    2.I found the USB cable is very short, what original intention is? Long will impact data transmission and reduce power? 3.I heard OV2640 is EOL, how to ensure M5cameraX/F continue product life?

Andy
