    Prototype Board Initial Setup There are several boards that are included with the Development System. The Carrier Boards have a HumDT Series transceiver on a daughter board with headers. These boards snap into sockets on the other boards, enabling the modules to be easily moved among the test boards. There are two Programming Docks that have a socket for a Carrier Board and a USB interface for connection to a PC.
