7" HMI Touch Display with ESP32-P4 - Wi-Fi 6, BLE 5, All-In-One with battery - Waveshare 30738

Description

The ESP32-P4-WIFI6 Touch LCD 7" with battery is a high-performance, integrated HMI (Human-Machine Interface) platform designed for applications requiring an advanced user interface, high computing performance, and secure wireless communication. The device is developed by Waveshare and is based on the modern ESP32-P4 microcontroller with RISC-V architecture.

The board is equipped with a 7-inch IPS display with a resolution of 720 x 1280 px, featuring a 10-point capacitive touch panel protected by toughened glass. This ensures high readability, wide viewing angles, and durability, which are essential in industrial control systems. Display orientation (landscape or portrait) can be changed via software configuration.

Wireless connectivity is provided by the ESP32-C6-MINI module, supporting Wi-Fi 6 (2.4 GHz) and Bluetooth 5 LE, ensuring stable data transmission and low latency. The platform works well as an operator panel, smart home terminal, or IoT interface.

The device offers advanced multimedia capabilities, including a built-in 5 MP front camera (OV5647), dual microphones with ES7210 echo-cancellation circuitry, and a built-in speaker. Combined with hardware support for image and audio processing (JPEG, ISP, H.264), this enables voice interfaces, speech recognition, and AI Speech Interaction applications.

The metal enclosure improves heat dissipation and increases reliability in industrial environments. Power is supplied via the USB-C port or the 3.7 V lithium battery included in the kit.
