RZ7899 dual motor drive module

1. Module introduction:
The dual-channel motor drive module based on the RZ7899 motor drive chip is smaller, cheaper, more compact and easier to use than most finished modules on the market.
2. Application scenarios:
It can be widely used in electronic design competitions, smart car competitions, engineering training competitions, personal DIY, etc. where DC motors, small motors, and fans are needed.
3. Product overview:
This module is cheap and solid, costing less than five yuan. Compared with several common modules on the market, the size is much smaller than L298N, and the withstand voltage and output current are much larger than TB6612. However, it is just as easy and convenient to use, and the measured chip works stably and reliably and is not easy to burn.
4. Product parameters:
Channel: dual;
Size: 1.8x2.0cm
Working voltage: 3.0V~25V (electrolytic capacitor voltage resistance needs to be considered);
Control voltage: 3.3V~5V compatible;
Output current: Single channel typical value 3A, Peak value 5A;
Features:
    1. With emergency stop function;
    2. With overheating protection function; 3. With overcurrent embedded current and short circuit protection functions;
    4. Built-in diode can release inductive reverse impulse current;
5. Usage method:
true value The table is as follows, using two channels of PWM to drive one motor:
6. Others:
I also drew the symbol and package of the module (I don’t know if you can find it)
7. Verify the actual object and use case (line patrol and obstacle avoidance car)
