General
The module can be used either as a) a serial LCD screen or b) a servo signal analyzer.

Connecting the module...

As a Serial Display
If the module is to be used either as a simple LCD display then only three wires are required –
Ground (-ve), Power (+ve), and signal (received signal/data).

If you want the serial display to act as a terminal, i.e. both displaying data from the host and sending data
back when the keys are pressed then a fourth wire is required (transmitted data).

Full details on using the module can be found in the datasheet here.

In Servo Signal Analyzer Mode
When used as a radio control servo signal monitor only three wires are required – Ground (-ve),
Power (+ve), and signal (received signal/data).

Figure C

This connection can be made with a standard R/C-style interconnect lead as shown above.
