1.4.7. Analog 5V Encoder (and Limit Switch) Breakout
The Analog 5V Breakout is for wiring a 5V analog sensor and limit switches. What makes this
breakout unique is that it scales a 5V analog signal to 3.3V using a resistor divider and voltage buffer.
Part Number: 217-4401(vexrobotics.com), am-2634(andymark.com)
5V Magnetic Shaft Encoders like the
U.S. Digital MA3 “just work” since the
breakout shifts the encoders native 5V
output to a Talon SRX compliant 3.3V
signal.
The top side has the 5V power, signal,
and ground pads for the analog sensor.
A ribbon cable should be used to
connect the Talon SRX to the breakout.
Tip: The selected colors in the diagram
match a typical cable harness colors for
some U.S. Digital Magnetic Encoders.
Additionally, the limit switch
pads are also available on
the top side. Note that the
reverse limit switch is on the
left side.
On the bottom are two additional ground
pads to pair with the limit switch pads.
Although normally open switches are
illustrated, normally closed switches can
also be used.
