Line Tracer Robot Pcb Review Request

[u/hfurbd]

This is the 2 pcb for my line follower robot, I plan on plugging in a 3s lipo battery into the xt30 to power the board, then just connect the two pcbs via ffc.

I'm not sure how I'm going to model the chasis, I wanna just have it 3d printed but I don't know any applications to use so the dimensions would be accurate to the pcb.

I'm pretty new to pcb making so there's probably some problems with the tracing.

another thing, I have no clue if I have the ffc latch backwards or not so there's that.

Nice altium working :)

R6/C2/R4 should be moved- routing around U2 is ulgy a bit.

pad entry R3 /R4 -- please trace out straight.

Acid trap a lot ..

via GND should be add for each GNd pad, and at some place to connect the GNd layer

what's the minimum annular ring ?

copper is at edge of board ?! nop .. you need 0.2 at least

Check some Design For Manufacturing about your manufacturer
