Wireless Screen Mirroring
Paired with the ESP32-C6 chip, it achieves wireless transmission through Wi-Fi; for more complex wireless scenarios, the ESP32-C5 chip supporting dual-band Wi-Fi 6 (2.4 & 5 GHz) can be used for a more stable connection. Meanwhile, the ESP32-P4 also supports data forwarding via Ethernet interface, providing users with more flexible options.
Supports resolutions up to 720P and refresh rates of 40Hz.
Connection method: Users only need to connect their computer or phone to the ESP32-P4 HDMI casting adapter wirelessly via the app and plug its HDMI interface into the screen interface to easily achieve quick casting, suitable for meeting presentations, remote work, and home viewing.

USB + HDMI Secondary Screen Expansion
The ESP32-P4 has a built-in high-speed USB interface.
Supports resolutions up to 720P and refresh rates of 30Hz, as well as 1080P resolution and 15Hz refresh rate.
Connection method: Connect via high-speed USB to the computer while connecting the HDMI interface to the large screen to achieve secondary screen expansion. Supports independent multimedia playback, easily displaying multimedia content. Suitable for video transmission, real-time monitoring, and multimedia applications.
-
Independent Multimedia Playback
Equipped with an SD card slot, supporting SD card reading.
Supports resolutions up to 720P and 60Hz refresh rates, as well as 1080P resolution and 60Hz refresh rates.
Connection method: Insert the SD card and connect the device to the HDMI interface, allowing direct playback of photos or videos without additional device support. Suitable for advertising deployment applications.
