Interface / Pinout Definition
All control and audio is interfaced via a single connector JP1. It is
intended to connect to a control board allowing firmware to control the
channels selection as well as the power.

Design considerations
The module is intended to interface to a control board that will
-
send the required command to select the desired channel. This
can be achieved using a simple push button switch interface
however the architecture of the interface enables the interface to
be controlled by a micro controller. Ideally you should develop
an interface that will provide feedback to the user, possibly by
way of an OSD, to indicate which channel the transmitter is
currently set to.
In order to disable the FM transmission as well as removing the
-
5VDC supply, the data lines (SEL2_A, SEL1_A, and Load) should
be held low.
