• Information: Features: ★ This module uses ST's L298N as the main riding chip, which has the characteristics of strong using ability, low heat generation and powerful anti-interference ability ★ This module can use the integrated 78M05 to take strength through the pressure energy supply part, but as a way to avoid damage to the voltage regulator chip, when utilizing a power voltage more than 12V, please use an exterior 5V common sense strength supply ★ This module uses large-capacity filter out capacitors and freewheeling defense diodes, which might upgrade reliability L298N is a high voltage, high recent motor driving force chip produced by ST Company The chip makes use of a 15-pin package The leading elements are: high operating voltage, most operating voltage as much as 46V; broad output current, instantaneous peak latest as much as 3A, continuous operating recent 2A; rated power 25W The high-voltage and high-current full-bridge motive force with two H-bridges can be utilized to drive inductive lots similar to DC motors, stepper motors, relay coils, and so forth ; it is managed by common common sense level signals; There is a common sense strength enter terminal that allows or prohibits the gadget to paintings without being affected by the enter signal, in order that the inner good judgment circuit part works at a low voltage; it may be connected to a detection resistor to feed again the replace to the management circuit Use L298N chip power motor, the chip can power a two-phase stepper motor or four-phase stepper motor, can also power two DC motors Instructions / Precautions Port function diagram This module integrates a built-in 5V strength delivery When your using voltage is 7V-35V, you may enable the onboard 5V common sense strength supply When utilizing the onboard 5V strength supply, the + 5V power delivery in the interface shouldn't enter voltage, but you could possibly draw 5V voltage for external use When ENA is enabled, IN1 IN2 controls OUT1 OUT2 When ENB is enabled, IN3 IN4 controls OUT3 OUT4
