What’s my project about?

I’ve designed a custom PCB around the ESP32-S3, a powerful microcontroller with both Wi-Fi and Bluetooth capabilities. My project involves using the ESP32-S3 to create a [specific project type, e.g., smart home device, wearable, sensor network], which will enable remote control, monitoring, or data collection via wireless communication.

Why did I decide to make it?

I wanted to create a custom PCB because:

I had specific requirements that weren’t easily met by off-the-shelf development boards, like a particular form factor, more I/O pins, or unique connectors.

Cost-efficiency was important, especially if I plan to scale the project. Creating a custom PCB is more affordable in the long run.

I wanted to learn more about PCB design and electronics while experimenting with integrating different sensors and peripherals.

I needed full control over the design, making sure that everything from the power supply to the sensor connections was perfectly suited for my project.

How does it work?

The ESP32-S3 on my custom PCB controls the entire system. Here's a simplified breakdown of how it works:

Powering the board: The board is powered either via an external supply or a battery. I’ve included a voltage regulator to ensure the ESP32-S3 gets the correct voltage.

Sensor integration: I’ve connected various sensors (e.g., temperature, humidity, motion) to the PCB. The ESP32-S3 reads data from these sensors and processes it.

Wireless communication: The ESP32-S3 uses its Wi-Fi and Bluetooth capabilities to send data to a cloud platform, a smartphone app, or another device. I can monitor or control the system remotely.

User Interface: Depending on the project, I may have buttons, a touch screen, or LEDs to display information and allow for user input or control.

For example, in my [smart home automation project], I would use the board to control lights or fans from anywhere via an app or automated routines.
