Mount Meadow the F7 Test board (pogo board)
Cut JP101 & JP102 if you haven't already
Connect a microUSB cable to the Meadow Micro F7
Connect a microUSB cable to the connecter on the test board labelled "EDGE"
Open a terminal and connect it to the serial port for the EDGE connection (115,200, data bits 8, parity none, stop bits 1) CP210x on Windows

Put Meadow into DFU mode (disconnect, hold the boot button, add power, release boot button)
Verify Meadow is in DFU mode: dfu-util --list
