ESP32-P4 7" HMI AI Display: Dual-Chip, Wi-Fi 6 & Edge AI Vision
The CrowPanel Advance ESP32-P4 HMI series is a high-performance AI-powered intelligent interactive terminal designed for demanding applications. Its innovative dual-chip architecture combines powerful computing power, rich multimedia features, and ultimate expansion flexibility, making it the ideal core for driving the next generation of smart devices.
This 7-inch display is powered by the RISC-V-based ESP32-P4 SoC, featuring both high-performance and low-power cores, operating at frequencies up to 400MHz. Combined with the generous storage capacity of 16MB Flash and 32MB PSRAM, it provides ample power for complex graphical interfaces and real-time AI tasks.
The onboard ESP32-C6-MINI-1 module supports 2.4GHz Wi-Fi 6 and Bluetooth 5.3, ensuring stable and reliable connectivity with excellent power consumption.
The 7-inch IPS touchscreen integrates capacitive touch technology, providing an intuitive user experience. The integrated 2-megapixel MIPI-CSIcamera (optional) not only supports high-definition image capture but also efficiently runs edge AI applications such as real-time facial recognition and dynamic object tracking.
The onboard NS4168 audio codec and single-microphone array provide high-fidelity playback and accurate far-field voice recognition. Equipped with dual-channel speakers, it lays a solid foundation for voice interaction and is suitable for scenarios such as voice assistants and smart home control.
The 7-inch screen also offers ultimate expandability. Equipped with dual USB-C ports (UART adapter/USB 2.0 Device), 11pin GPIO, multiple Crowtail ports (supporting I2C/UART protocols), and interchangeable wireless module slots (supporting Thread, Zigbee, etc.), it easily adapts to various sensors and communication protocols.
Whether you're building a smart home central control, an industrial automation panel, or an AIoT edge device, the CrowPanel Advanced 7" delivers the performance and flexibility you need.
Why choose the P4 HMI series?
Compared to previous generations(Basic/Advanced ESP32-S3), the ESP32-P4 HMI series achieves a significant leap in machine learning inference and real-time data processing performance through an upgraded processor and AI instruction set. Whether it's a smart home central control, an industrial control panel, a commercial display device, or an AIoT application in Industry 4.0, its comprehensive peripheral support can provide excellent solutions to help you quickly build powerful and interactive smart products.
Note: The ESP32 P4 Official is not supported by the PlatformIO platform.
