Hi, I'm CRAZY PROF. Previously I have designed a communication development pcb for microchip 16f or 18f series microcontrollers.

This motor driver is designed to save your pcb space.

Many Arduino development shield PCBs connect to Arduino via female-male cables.

I have specifically designed the Arduino uno or mega on the L298N driver card takes up less space and requires less wiring, and also re-use of all pins of the arduino was targeted.

That is, 1 cable can normally be attached to the arduino pin. Additional connections to the same pin may be required if necessary. As you can see in my design, there are 2 pieces of the same arduino pin. When one pin is used, another cable can be plugged back into the same pin.

Now let's move on to the features of PCB ...

* It is within 10x10cm size suitable for PCBWAY campaign.

* 2 layers PCB

* L298N operating voltage (5v) can be taken from arduino or external supply via Jumper.

* L298N can be supplied externally with 78l05 regulator up to 30v.

* In most L298N pcb, current limiting resistor is not installed or short-circuited. With this in mind, I have separated the SENSE-A and SENSE-B pins and made analogue current measurement possible.

* PCB in this state can drive stepper motor or dc motor. If desired, a single motor can be connected to the bridge.

* L298N heatsink is reserved for the outside of the pcb.

* In case of sponsorship, I will provide free transmission to the required robotics project developers or technical lab laboratories.

I would also like to thank PCBWAY for giving us this opportunity ...
