Connect your DC motor to the motor output terminals. For analog control, apply a 0-5V signal to the analog input pin from a potentiometer or microcontroller DAC. For serial control, connect a UART interface at 2400-115200 baud and send ASCII commands to set motor speed (-127 to 127 for full reverse to full forward). For USB programming and configuration, connect the micro-USB port to your computer and use the official RoboClaw configuration software to set parameters, calibrate analog inputs, and monitor real-time telemetry.\u003c\/p\u003e\n\n\u003cp\u003eAdvanced users can implement closed-loop speed control by reading the motor current feedback and adjusting PWM commands accordingly. The device supports configurable acceleration ramps, preventing sudden current spikes that damage gearboxes or mechanical linkages. Always monitor the thermal indicator during initial testing at maximum current to ensure adequate heatsinking. For applications exceeding 30A continuous current, consider using multiple RoboClaw Solo units in parallel with current-sharing resistors, or upgrade to the dual-channel RoboClaw 2x60A model.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between the Pololu 3290 and 3291 models?\u003c\/summary\u003e\n\u003cp\u003eThe Pololu 3290 is the standard RoboClaw Solo with full feature set. The 3291 variant is functionally identical with identical specifications and firmware. Both models support the same communication protocols, current ratings, and voltage ranges. Selection between the two depends on availability and your specific procurement requirements, as they are interchangeable for most applications.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I control multiple motors independently with a single RoboClaw Solo?\u003c\/summary\u003e\n\u003cp\u003eNo, the RoboClaw Solo controls one DC motor channel only. For two independent motors, you require either two RoboClaw Solo units or a single RoboClaw 2x60A dual-channel controller. However, you can connect multiple Solo units to the same serial bus and address them individually via unique device IDs set through the configuration software.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat happens if I exceed the 30A continuous current rating?\u003c\/summary\u003e\n\u003cp\u003eThe controller includes over-current protection that triggers automatic shutdown when current exceeds safe limits, protecting the internal MOSFETs and circuitry. The device will resume operation after cooling. For applications requiring sustained currents above 30A, upgrade to the RoboClaw 2x60A model or implement external current limiting using series resistors or dedicated current-limiting power supplies.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the RoboClaw Solo work with brushless DC motors?\u003c\/summary\u003e\n\u003cp\u003eNo, the RoboClaw Solo is designed exclusively for brushed DC motors. Brushless DC motors require a dedicated ESC (Electronic Speed Controller) with commutation logic. Using this controller with brushless motors will result in erratic behavior and potential damage. For brushless motor control, select appropriate ESC models rated for your motor specifications.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use this controller with a 48V power supply?\u003c\/summary\u003e\n\u003cp\u003eNo, the maximum rated supply voltage is 30V DC. Applying 48V will immediately damage the internal voltage regulators and MOSFETs. For high-voltage applications above 30V, you must use dedicated controllers rated for that voltage range or implement a DC-DC converter to step down the voltage to safe levels.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
