The PLD USB C Meter is something I'm designing for technicians such as myself because very often I need to keep track of the USB-C current levels during a diagnosis of a device. While there are existing meters which can do the same thing via Bluetooth, I find BT/BLE to be considerably more problematic than just having a direct data link to the PCB via a USB cable.
In this stream I'm adjusting the existing software to suit the new board design ( after the original hackjob proto ) as well as picking up the "Ooops" events where I forgot some things with the board layout, such as the INA219 addressing pins.
