ESP32-P4-WIFI6 development module with 7" HMI touch display
HMI module based on the high-performance ESP32-P4 (RISC-V) microcontroller with a 7-inch capacitive IPS touch screen with a resolution of 720 × 1280. The board is a fully integrated solution – it features a built-in 5MP front camera, Wi-Fi 6 and BLE 5 communication module, as well as dual microphones and an audio system.
Key features:
- High-performance ESP32-P4 microcontroller with 32-bit RISC-V architecture.
- IPS display 7" (720 × 1280) with a tempered glass panel and precise 10-point touch.
- Built-in 5MP front camera (OV5647).
- Wi-Fi 6 and Bluetooth 5 (LE) thanks to the built-in ESP32-C6 module.
- Integrated audio system with dual microphone (hardware echo cancellation) and support for an external speaker.
- Built-in memory: 32MB PSRAM integrated into the chip and additional 32MB Nor Flash on the board.
- Extensive peripheral interfaces: USB 2.0 OTG HS, microSD (TF) card slot, MIPI-CSI connectors.
- Advanced security features: Secure Boot, Flash encryption, TRNG, and hardware cryptographic accelerators.
- Durable metal back housing for easy heat dissipation and mounting.
Integrated 5MP front camera
The module is equipped with a high-quality OV5647 sensor (1/4 inch) with a 72.9° field of view, located in the front part of the frame. It allows for capturing static images at a resolution of up to 2592 × 1944 pixels and video recording (including 1920 × 1080p @ 30fps). It provides an excellent base for projects related to video doorbells, face recognition, or monitoring.
Extensive audio path and excellent cooling
On board is an advanced ES8311 audio codec connected to a dedicated ES7210 echo cancellation chip. Together with the dual microphone array, the board guarantees high-quality recorded sound and effective ambient noise suppression. The entire electronics assembly is covered by a solid, fully metal housing that acts as a large heatsink and ensures stable operation even during intensive use of the P4 processor.
