-2019-06-02 - Using a Raspberry Pi as AVR programmer. I connected it with power on the QCX, did not use the 5V supply from the Raspberry Pi. 
  
-{{:img_1746.jpg?nolink&600|}}+Using a Raspberry Pi board as AVR programmer to update the QRP Labs QCX transceiver's firmware. The power draw from the QCX to the RPi seemed a bit too much, so I did not use the RPi 5v output.
