PCBWAY make high quality prototyping PCBs for people all over the world. Try it for your self and get 10 PCBs for just $5 at PCBWAY with very great quality, Thanks PCBWAY. The Motor Shield for ESP32-Cam that I developed in this project uses PCBWAY PCB services. In this instructable, I will show you how to build Camera WiFi Robot Car use ESP32-Cam. Let's get started!
Step 1: Design PCB Use Autodesk Eagle Software
To design a PCB use Autodesk Eagle software, which is a CAD program specifically designed for making circuit boards. This software is free for 2-sided boards up to 80cm². This should be more than enough area for any hobby project.You can download Eagle from Autodesk's website, and you will also need to sign up for a free Autodesk account.

You can follow Circuit Board Design Class.
Step 2: Order PCB on PCBWAY
To make this project you need to order a prototype PCB on PCBWAY. How to order is very easy and you will get 10 Pcs PCB for $5 with very great PCB quality.
Step to Order:
1. SignUp/Log in on pcbway.com
2. Open this PCB project link ESP32 Camera Motor Shield
3. Click Add to cart.
4. Wait moment for PCB review, then Click Check Out.
Step 3: Parts List
Here are the components that you will need to make ESP32 Cam Motor Shield:
* 1 x PCB ESP32-Cam Motor Shield (PCBWAY)
* 1 x ESP32-Cam Board
* 1 x USB to TTL CP2102 Module
* 1 x IC L293D Driver Motor
* 2 x Transistor NPN BC547
* 1 x Voltage Regulator 5V AMS1117
* 1 x Diode 1N4001
* 1 x LED Red 3mm
* 5 x Resistor 10K Ohm
* 2 x Resistor 1K Ohm
* 1 x Capacitor 100uF/16V
* 1 x Active Buzzer 5V
* 1 x Tact Switch
* 1 x SPDT Slide Switch
* 3 x 2 Pin Terminal Block Screw
* 4 x 10 pin Male Header
* 1 x 8 pin Female Header
* 1 x 6 pin Female Header
* 2 x 8 pin Long Legs Female Header
Step 4: Solder SMD Component (AMS1117 5V)
This project has one SMD component, it is not too difficult to solder because the size of the SMD component is quite large, so don't worry.
You will need tweezers as a tool to hold the components when soldered.
Step 5: Place the Components
After finish solder SMD component, next attach other trough hole components on the PCB following the pictures and symbols on the PCB, for details you can follow step by step in the video.
Step 6: Soldering
Solder all the component legs on the back of the PCB, for details you can follow step by step in the video.
After finish solder, cut all the long legs of the component wire
Step 7: Attach Short Leg of the Female Header
Bend the short leg of the female header into an elbow 90 degrees, then attach it on the PCB pin hole as shown. then solder it
Step 8: Attach Long Leg of the Female Header
Bend the long leg of the female header into an elbow 90 degrees. Attach it to other straight long leg of the female header as shown.
Before applying glue, the continuity of each pin is connected first.
Then by using the ESP32-Cam as a mold to hold the pin header, you can solder to the PCB.
Step 9: Attach IC, ESP32-Cam & USB to TTL Module
Install IC L293D (dual motor driver) on the IC socket, see its position do not reverse.
Attach the USB to TTL CP2102 module which already has a male pin header into the female header socket that leads outward.
Install the ESP32-cam board on the female header socket as shown.
Step 10: PCB Mainboard Is Ready
Your PCB mainboard is ready as controller Robot Wifi Camera.
Step 11: Attach Mainboard Into Chassis
You can use a custom chassis that you have or you made yourself. 375
