Espressif released a new generation of MCU chip ESP32-P4, and the ESP32-P4 development board also debuted. In this article, LCSC supplier Wireless-tag will explain the ESP32-P4 multimedia development board.
Overview of ESP32-P4 Development Board
Espressif’s ESP32-P4_Function_EV_Board development board is a multimedia development board designed based on the ESP32-P4 chip. The ESP32-P4 has a dual-core 400 MHz RISC-V processor and supports 32 MB PSRAM. In addition, the ESP32-P4 supports USB 2.0 standards, MIPI-CSI/DSI, H264 Encoder, and other peripherals, which can meet customers’ development needs for low-cost, low-power multimedia products.
Most of the module pins on the board are brought out to header pins. It allows developers to easily connect various devices through jumpers according to actual needs. The development board can also be plugged into a breadboard for use.
The ESP32-C6-MINI-1 module on the development board can serve for Wi-Fi and Bluetooth communications; the two ESP-Pro interfaces can serve for programming and debugging the ESP32-P4 chip and ESP32-C6 module respectively; and through the ESP32-P4 external audio Codec chip, audio PA, microphone, headphone and speaker interfaces, we can achieve a variety of audio processing and applications; two high-speed USB2.0 interfaces support Type-A and Type-C respectively, both of which can serve to communicate with the ESP32-P4 chip; MIPI CSI/DSI interfaces serve for external camera modules and LCD expansion boards respectively to achieve image and video transmission and display. In addition, the board also has 16MB of SPI Flash, a battery interface, a MicroSD card slot, multiple sets of peripheral interface pins, and other components.
