Actuonix Linear Actuator Control Board

Actuonix Linear Actuator Control Board

The Linear Actuator Control Board (LAC) is a versatile, standalone, closed-loop control board engineered specifically to interface with the Actuonix P-series line of micro linear actuators. Managing raw DC motor directional shifts and deciphering analog feedback curves can introduce significant programming overhead. Fortunately, the LAC eliminates this complexity by automatically handling all internal proportional-integral-derivative (PID) loop calculations. It can read input signals ranging from standard USB commands to analog voltage sweeps. Consequently, developers can implement high-accuracy linear positioning systems using as little as a single digital or analog output from an external controller.

Key Features

• Standalone Closed-Loop Processing: Manages internal position-tracking loops natively, saving valuable microchip overhead on your master controller.

• Multi-Signal Hardware Detection: Automatically accepts USB data, $0-5\text{V}$ voltage sweeps, 4-20 mA current loops, RC hobby servo signals, and digital PWM streams.

• Onboard Potentiometer Calibration: Integrated trim pots allow you to manually adjust actuator speed, system sensitivity, and physical stroke limits without writing code.

• Flexible Operating Layouts: Functions seamlessly as an external interface terminal or as a completely isolated, standalone motion controller.

• Comprehensive P-Series Compatibility: Works flawlessly with every 6-volt and 12-volt P-series micro linear actuator module.

• Protective Overcurrent Circuitry: Monitors current levels dynamically to prevent internal component damage if an actuator stalls.

• Compact Single-Board Design: Small physical layout allows for neat mounting inside crowded control panels or robotic chassis.

Applications

Automation engineers frequently deploy the Linear Actuator Control Board to quickly calibrate advanced medical laboratory instruments and automated optical test fixtures. It bridges the gap between industrial Programmable Logic Controllers (PLCs) or Arduino microcontrollers and micro-motion devices. RC hobbyists and drone builders use the board to convert standard radio-control receiver outputs into precise linear motion for landing gear or cargo bays. It is also an ideal tool for setting up automated window actuators, building custom mechanical safety locks, and assembling small-scale educational robotics kits.

Configuration and System Integration

The physical layout of the LAC is optimized for rapid hardware integration. When using it in standalone mode, users can link a simple external potentiometer to the board to command linear movements across a matched scaling curve. For precision applications, downloading Actuonix’s configuration software via the onboard USB port allows developers to fine-tune the internal firmware settings directly. To avoid data drops, ensure your external power supply matches the voltage rating of your connected P-series actuator (6 V or12 V DC) and can supply sufficient burst current under maximum mechanical loads.
