The OV5640 can be used if autofocus is required on the ESP32-CAM. Please note that there are different pinouts from some OV5640 manufacturers.
Check out the ESP32-CAM with OV5640 and the Arduino Library for it on my channel.

*Raspberry Pi using a battery pack
This is a test to see if the battery pack for Pi can operate in an environment that includes an HDMI 7-inch display. In short, 4B recommends using the battery pack without a display.

![ESP32-S3 USB Camera & Audio WebSocket Test: UVC + UAC Data Streaming Demo (ft. WebSocket)
In this project, I showcase how to connect a USB camera and microphone to the ESP32-S3, capturing both image and audio data using UVC (USB Video Class) and UAC (USB Audio Class). The ESP32-S3 streams raw image and audio data over a WebSocket connection, demonstrating a simple server for testing purposes.
**Important:** This WebSocket server is designed to help test raw data streaming but is not intended for real-time multimedia transmission. For actual simultaneous streaming of video and audio, a protocol like RTSP (Real-Time Streaming Protocol) is recommended.
In this demo:
- We connect a USB camera to ESP32-S3.
- Capture image and audio data via UVC and UAC.
- Stream raw data using a WebSocket server.
- Display the incoming audio and video packets in real-time on a client.
This test setup is useful for developers working on USB peripheral integration with ESP32 but requires further implementation for practical multimedia streaming.

![Offline Map Viewer with ESP32 and Round Display
This is a small project I put together to show local maps on a 4-inch round display using an ESP32. The map tiles are stored on an SD card, so it works without Wi-Fi.
It’s not meant to replace your phone — it’s just a fun way to learn and experiment. The project uses LVGL to draw map tiles, supports touch scrolling, and lets you adjust the zoom level. As you move the map, the latitude and longitude at the center update in real time.
The workflow is straightforward:
- Download map tiles with an offline map downloader.
- Convert them into RGB565 binaries for LVGL.
- Load them from the SD card inside an ESP-IDF project.
I also published a map_tiles component to the ESP registry to make it easier for others to try.
This is just a hobby project, but it could be a starting point for other ideas like offline GPS gadgets or simple map-based dashboards.

![My Air Quality Sensor, LVGL 9, [Ep.06] Draw IKEA UI, #ikea #airquality #esp32
I made a similar version of IKEAs air quality sensor, VINDSTYRKA, using ESP32 and an environmental sensor.
When studying UI/UX, I think it is essential to create code yourself. Through this, you can become familiar with what widgets to use and how to create and apply styles. In this project, Ill first complete the UI using LVGL, and in the next project, Ill explain how to update the screen by reading the necessary data from the sensor. Thank you.
