Pololu Simple - Manual (Page 5)

Two Pololu Simple Motor Controllers
enable mixed RC-control of Dagu Wild
Thumper 4WD all-terrain chassis.
• RC features:
◦ 1/4 µs pulse measurement resolution.
◦ Works with RC pulse frequencies from 10 to 333 Hz.
◦ Configurable parameters for determining what constitutes
an acceptable RC signal.
◦ Two RC channels allow for single-stick (mixed) motor
control, making it easy to use two simple motor controllers in
tandem on an RC-controlled differential-drive robot.
◦ RC channels can be used in any mode as limit or kill
switches (e.g. use an RC receiver to trigger a kill switch on
your autonomous robot).
◦ Battery elimination circuit (BEC) jumper can power the RC
receiver with 5 V or 3.3 V.
• Analog features:
◦ 0.8 mV (12-bit) measurement resolution.
◦ Works with 0 to 3.3 V inputs.
◦ Optional potentiometer/joystick disconnect detection.
◦ Two analog channels allow for single-stick (mixed) motor control, making it easy to use two simple
motor controllers in tandem on a joystick-controlled differential-drive robot.
◦ Analog channels can be used in any mode as limit or kill switches.

We do not recommend using the 18v7, 18v15, or 18v25 versions with 24 V batteries, which can significantly
exceed 24 V when fully charged. The 24v12 and 24v23 are the much more appropriate controller for 24 V
applications.
