[Review Request] - Arduino Nano Custom PCB Shield

Hi,

I recently completed my first PCB design, its essentially going from breadboard for my robotic arm to a PCB, saving on space and clutter. Important note of the design, its 4 potentiometers which feed analog inputs to the arduino nano, the nano converts the analog values into signals for the Servos thus allowing manual control of each individual motor. Power comes from J1, via a 5 Volt 6 Amp Power supply

Currently passes all design Role checks, but am concerned with a few things.

  1. is 59 MIL trace width large enough for a max 3.6 A load from the 4 servos that run the arm?

  2. routing at some places is long, I worked on positioning parts as best I could, but am unsure how to optimize it further to make the board smaller.

Any other feedback or issues would be greatly appreciated.

Schematic + PCB Review, First PCB design

Hi All,

Just made my first PCB for a robotic arm project I was working on, its rather simple, but the primary goal of this project was to get rid of the breadboard and create a custom shield for the Arduino Nano while getting familiar with Altium, that was used in the robotic arm project. The potentiometers are utilized for manual control for each individual motor while the DC barrel connector is used to power the servos, meant to be used with a 5 V 6 A power supply.

Thank you!
