Mini Brushed Motor ESC 3A 1A DC3.58.4V Bidirectional PWM Speed Controller Module with Forward Reverse Operation

1A and 3A Brushed Motor Simple ESC Micro Drive Module Compact bidirectional brushed ESC designed for reliable, proportional speed and direction control of small DC brushed motors and continuousrotation servos. Key benefits Small PCB construction for stable performance and long service life. Smooth, linear speed control compatible with common RC receivers and control systems. Two current options to match application needs: 1A continuous for tiny models and 3A continuous for larger micro projects. Bidirectional control with neutral PWM stop makes it suitable for forward and reverse operation without extra hardware. No potentiometer adjustment required; the digital circuit simplifies setup and reduces maintenance. Variants and technical specifications 1A variant Size: 12 x 8.5 mm Input voltage: DC 3.5 to 6 V Continuous current: 1 A; peak max 1.5 A PWM input range: 1000 to 2000 us Cable length: signal cable 200 mm; motor cable 20 mm Wiring: available with or without cable BEC output: none Direction: bidirectional, reversible Compatible motor type: brushed DC motor 3A variant Size: 20 x 17 mm Input voltage: DC 4.2 to 8.4 V Continuous current: 3 A; peak max 4 A PWM input range: 1000 to 2000 us; PWM 1500 us = stop Wiring: supplied without cable BEC output: none Direction: bidirectional, reversible; PWM 1500 us = stop Compatible motor type: brushed DC motor Control behavior The module interprets PWM around 1500 us as neutral. Values below 1500 us command forward rotation, with speed increasing as PWM decreases. Values above 1500 us command reverse rotation, with speed increasing as PWM increases. The module supports continuous rotation only and cannot provide positional control. Typical applications Miniature RC cars and small ground vehicles requiring compact forward and reverse motor control. Micro multirotors, mini drones and model aircraft that use small brushed motors or continuousrotation servos. 360degree continuousrotation servos and micro motor projects where proportional speed and reversible direction are needed. Installation and usage notes Read specifications carefully before installation to avoid improper connections or damage. Select the correct variant to avoid overloading the ESC and the driven mechanism. Provide a stable supply voltage within the specified range and ensure the power source can supply required current under load. Operation outside specified voltage or current limits may cause malfunction or permanent damage. Keep the module and its environment of dust, corrosive gases and excessive moisture to extend service life. Allow for a manual measurement tolerance of 0 to 3 mm in size specifications.
