12V 24V Motor Drive Board H-Bridge Motor Speed Controller Module Forward Reverse Rotation Motor Controller forSupport voltage 6.5V-27V, undervoltage protection, power supply ient interference suppression. Dual motor interface, each rated output current 7A. Similar to the L298 control logic, each support three-wire control enable, reverse and brake. The enable signal can be connected to PWM externally, and the forward and reverse control signal can be connected to the limit switch in series. The control signal uses the irrigation current drive mode, which supports the majority of single-chip microcomputer direct drive. All control signals are isolated by optical coupling. There's an electrostatic discharge loop. Power supply voltage range: DC 6.5V-27V Rated input voltage: DC 12V/24V Number of output channels: 2 way Rated output current per channel: 7A current per channel: 50A Maximum adaptive motor: 12V-40W 24V-120W Control signal voltage range: 3-6.5V Each control signal current: 3- 11mA Supported PWM range: 0-100% Support PIM frequency range: 0-10kHz Operating temperature: -25-80 Colour:As Shown Material:PC Package Contents: 1 x Motor Drive Board(Due to different product batches, the appearance , which does not affect the use) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
