Overview

You'll find me designing the PCB I'll be using in my final project. This PCB will be connected to the robot.

Resources

1. I got help from ChatGPT while trying to design the connection from the VL53L1X to the XIAO ESP32C6.
2. I got help from ChatGPT while learning how to write code to turn a continuous servo.
3. I used Kicad to design my PCB.
4. I used a SRM-20 to mill my PCB.
5. I used Arduino IDE to write code.
6. I used Inkscape to help with getting the milling toolpath ready.
7. I used Mods to create the milling toolpath.

PCB Design

Parts:

1. 2 Continuous Servo Motors (MG 996R)
2. 1 XIAO ESP32C6
3. 1 VL53L1X
4. 1 Polarized Capacitor (EEE-FN1E101UL)

In the PCB, there will be 3 horizontal pin headers for each of the servos.

XIAO ESP32C6 pins:

Pins of the VL53L1X breakout board:

I imported the components and connected them as needed.

I positioned the components and ran a DRC.

Except some warnings, there wasn't anything bad. The warnings aren't important, so the design of this PCB is done!

Milling/Soldering

I'll be using Mods when creating the toolpath of this PCB. You can find the process at which I created the toolpath in my week 8 assignment. However, this time, I didn't change the setting in the Home section of Mods since that created a problem at that time (week 8).

The F.Cu layer:

The Edge.Cuts layer:

I preapared the copper clad.

I preapared the machine.

The PCB is cut.

I soldered the parts.

Coding/Testing

I started by downloading this library in Arduino IDE.

I got this code from ChatGPT, which is for making a continuous servo turn.

The servo is turning:
