Product description:

Double H driver module uses  L298N dual full-bridge driver, an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the  lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.

Product parameters:

- Light weight, small dimension
- Super driver capacity
- FWD protection
- Heavy load Heat sink
- 2 current probe port
- Power selection switch
- 4 pull up resistor switch
- 2 DC motor/ 4 coil dual phase stepper motor output
- Motor direction indication LED
- 4 standard mounting hole
1. Driver chip: L298N double H bridge DC motor driver chip
2. Drive part terminal power supply range Vs: +5V to +35V (If you need to take power inside the board, the power supply range is Vs: +7V ~ +35V)
3. Drive part of the peak current: 2A
4. Logic part terminal power supply range Vss: +5V ~ +7V (can take power +5V inside the board)
5. Logic part operating current range: 0 ~ 36mA
6. Control signal input voltage range:
   Low level: -0.3V≤Vin≤1.5V
   High level: 2.3V≤Vin≤Vss
7. Enable signal input voltage range:
   Low level: -0.3≤Vin≤1.5V (control signal is invalid)
   High level: 2.3V ≤ Vin ≤ Vss (control signal is valid)
8. Large power consumption: 20W (at temperature T=75°C)
9. Storage temperature: -25 ° C ~ +130 ° C
10. Driver board size: 48mmx43mmx33mm (with fixed copper post and heat sink height)
11. Driver board weight: 33g
12. Other extensions: control direction indicator, power take-off interface in the logic part
Instructions for Use:
1. Stepper motor drive:
 The ENA and ENB on the board are active high, and the level here refers to the TTL level. ENA is the enable of A1 and A2, and ENB is the enable of B1 and IB2. BJ is connected to the common end of the stepper motor.
2. Stepper motor control logic:
Among them, A, B, C, and D are the four coils of the stepping motor, and 1 means that current flows, and 0 means no current flows.
