#25 Fixing Lookee A2 blood pressure monitor to work with a USB-C cable
Out of the box this device only works with a usbA-usbC cable, because they're designed to provide 5V no matter what, however usbC-usbC cable that's up to spec and connected to a proper usbC power supply won't provide any voltage. To fix it, you have to add 5.1k pulldown resistors on CC1 and CC2 lines as per USB spec.

#12 Update: Making USB-C deliver 5V
Переглядів 11 тис.2 роки тому
After some googling and some testing I finally figured out that the lines CC1 and CC2 are shorted on these breakout boards. Severing the connection between them and adding two pull-down resistors makes it a usable 5V connector. You will also probably need 1206 size resistors for the reverse side: s.click.aliexpress.com/e/_AAAqGp

  • @gusmartin6053
    @gusmartin6053 6 місяців тому

    It looks like you only added the 5.1K resistor to one of the CC pins. Doing this will cause a USB-C to USB-C cable to work in one orientation but will not work when the connector is flipped 180deg. C to C cables only have one CC wire which allows for power negotiation as well as for determining connector orientation by observing which CC pin has a connection and which is open. You need to add a 5.1k to both CC1 and CC2, or you can also short CC1 and CC2 together, then use one 5.1k to ground. Shorting the CC pins is not normally done but in a simple power application like this, it's not a problem. I realize this video is a couple years old now, but thought that explanation may help someone who is confused by this.

    • @UNgineering
      @UNgineering 6 місяців тому

      You are right, I added only one 5.1k resistor because this board has cc1 and cc2 lines shorted together, which was part of the problem. I posted an update to it where I separated the lines and added separate resistors to each one (#12). Thanks for your detailed explanation!

    Does rpi zero have a built-in overvoltage / overcurrent protection? Or it relies on the quality of power supply and will potentially fry the board if there are any issues with PD mode selection on the charger side? Asking because I already fried couple of projects by adding type-c ports with pull-down resistors and plugging them into 65W GaN charger

    • @UNgineering
      @UNgineering 7 місяців тому

      I don’t think there is on the Zero. But if the power supply is made to spec, it should only provide 5V when it detects the pulldown resistors.
