Disconnecting mEDBG
The target device can be completely separated from the mEDBG, but this requires some small modifications to the
board using a soldering iron. By removing the resistors in the sections shown in the figure below, the mEDBG is
completely disconnected from the target controller. If desired to connect the mEDBG again, solder in 0Ω resistors or
solder in 100-mil headers on the header footprints and use wire-straps to connect the interfaces.
