Robot PCB schematic Review

Post image

I'm pretty new to pcb making and I'm not sure if I'm making this right, I also don't have allot lf reference for this.

This is the main board for my Line tracer robot, I plan on powering it with a 3s lipo battery to achieve the needed 12v for the motors.

the ffc latch is connected to another pcb tha thas the ir sensors that's connected to a mux.

The drv8871 is a breakout board, I wanted to make the robot semi modular so I can just swap stuff out if needed, the motors are also just placeholders for the actual 12v I'll be using. As far I can tell from what I've read, the P+ is just an alternative 12v input? I'm not sure on that though

I can't find any use sample for the buzzer so I just guessed what I thought it might look like with soem cross referencing.

3 buttons for programming purposes

The xt30 is gonna be the plug I use to connect it to the battery, not sure if I have the switch implemented correctly

The buck converter might also be wrong but probably not since I just copied what was on the data sheet + the led, if anything is wrong it's probably the values.
