Notes from hacking today:

  • Run custom I2C slave 7-17V only. Need at least 7 to power on.
  • Use the EveryCircuit iPhone app
  • Grounds on board are connected together

Design of the I2C slave protoboard. This slave measures analog voltage 0-5V from an input voltage of 7-17V. The device is powered from the monitored source. A Tessel 2 is connected as the I2C master device for data logging.
