Minutes

• small board review (Andrew Fearing )

  • happened 13 Apr 2021

  • Andrew Fearing designed McCoy v1.1 based on feedback

  • pins for all GPIOs 0-15

  • antenna pins removed, as well as extra resistors

  • 2 layers

  • antenna: current same .1 inch through hole?

  • discussion about which to use battery

  • additional remarks

    • Austin Patel GPIO1 can output optical data, GPIO8/GPIO9 is active light/low, we want to be able to short GPIO1+GPIO8, ten GPIO1+GPIO9 to be able to do lighthouse.

      • we could drop of the GND pins and rewire two extra GPIO1 signals to pins

    • moving the pins from J5 into J4 (GPO_ZERO)

    • make sure pins on J4 are enough to connect to an nRF52840

• BigBoard review (Joshua Alexander )

  • Teensy pins plus GPIO pins

  • 22 pin header, aligned to the Teensy pinout

  • discussion about how both Teensy and nRF52840-DK can be used, using the same ribbon cable, to program both the McCoy and big board

  • J10 is used for current consumption

  • suggestions

    • suggestion to group pins into a small number of pins

    • have ADC in close to the development region
