The Raspberry Pi 3B+ is a compact and powerful single-board computer. It comes with built-in Wi-Fi, Bluetooth, and full-size HDMI. This board is great for many projects—from DIY electronics to smart home systems and light desktop setups. It runs using a microSD card that stores the operating system and files. The Pi 3B+ offers excellent performance and works well with a wide range of accessories and displays.

To add a display, the Waveshare 13.3-inch HDMI LCD is an ideal choice. It connects via HDMI for video and uses a USB cable for touch input. The screen is large, sharp, and responsive. This makes it perfect for dashboards, user interfaces, media centers, or portable workstations. It adds interactivity and improves usability, especially when more screen space is needed.

In this guide, you’ll learn how to prepare the microSD card with Raspberry Pi OS. You’ll also connect the 13.3-inch LCD and configure the display. After a few simple steps, your Raspberry Pi 3B+ and Waveshare LCD will be ready for your next creative build.

Here’s a quick guide for you on how to set up your Raspberry Pi 3B+ with a 13.3 inch HDMI LCD (H).

When setting up your Raspberry Pi 3B+ with a 13.3 inch HDMI LCD (H) Waveshare, it’s important to start with a properly formatted microSD card. If the card is new or has been used in another device, you should quickly reformat it using the SDCard.org formatter. This step ensures the card is clean and ready for the Raspberry Pi OS. Make sure to choose the Quick Format and Overwrite Format options for the best results, as this helps prevent errors during the installation process.

Start by downloading the Raspberry Pi OS from the official Raspberry Pi website. Then, use the Raspberry Pi Imager to write the OS onto a microSD card. For best compatibility with the Raspberry Pi 3B+, choose the 32-bit version of the operating system.

Choose “YES” if you want to pre-configure settings

Choose “YES” if you are ready to erase all data on the SDHC Card and proceed with flashing the Raspberry Pi OS.

This is where you’ll add the settings needed to make the 13.3-inch HDMI LCD (H) (with case) Waveshare work properly. Just copy this block and paste it directly into your config.txt file to save time:
