USB Interface Hardware
The Buck GUI software is designed to work with the LinkM™ USB to I
2
C™ interface device
manufactured by ThingM. Information about the LinkM can be found at the ThingM
. A
Windows‑based PC is required with a dedicated USB port. The use of USB expansion ports, especially
those that are heavily loaded, is not recommended.
The LinkM interface can be mounted directly to the PI33xx‑xx evaluation board using a straight
4‑pin header (see Figure 1). Users who wish to connect the LinkM in this manner will need to use a
male‑to‑female USB extension cable. This method works very well and is the preferred method. Other
users may wish to probe the I
2
C bus or connect to it with ball clips. For this option, the LinkM data
sheet describes the recommended connectors to build such a cable.
