L298 2A Dual Motor Driver Module With PWM Control
L298 2A Dual Motor Driver Module with PWM Control (6 ~ 12V) which is the revised version of the DF-MDV1.0. Its performance has been improved greatly. It can bear a larger current due to the increased heat sink dissipation. It is easy to control, using LGS’s outstanding high-power motor driver chip, the L298N. This chip allows for direct drive of two bi-directional DC motors and incorporates high-speed short diodes for protection. Drive current up to 2A per motor output. The driver uses a broad-brush design to reduce wire resistance.
H-bridges are typically used in controlling the motor’s speed and direction but can be used for other projects such as driving the brightness of certain lighting projects such as high-powered LED arrays.
How it works:
An H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM).
Pulse Width Modulation is a means of controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied too heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM.
