Product Features

This series of products is a dual-core and single-core RISC-V high-performance development board based on the ESP32-P4 chip. It is equipped with a 3.4-inch 800 × 800 resolution IPS circular touch screen and supports a variety of human-computer interaction interfaces, including MIPI-CSI (integrated image signal processor ISP). It also supports USB OTG 2.0 HS for high-speed connection, and has an onboard 40PIN GPIO expansion interface, which is compatible with some Raspberry Pi HAT expansion boards to achieve a wider range of application adaptation. The ESP32-P4 chip integrates digital signature peripherals and a dedicated key management unit to ensure the security of data and operations. It is designed for high-performance and high-security applications, and fully meets the higher requirements of embedded applications for human-computer interface support, edge computing capabilities, and IO connection characteristics.

High-performance MCUs with RISC-V 32-bit dual-core and single-core processors
128 KB HP ROM，16 KB LP ROM，768 KB HP L2MEM，32 KB LP SRAM，8 KB TCM
Powerful image and voice processing capabilities, image and voice processing interfaces include JPEG codec, pixel processing accelerator (PPA), image signal processor (ISP), H264 video encoder
32MB PSRAM is stacked inside the chip package, and 32MB Nor Flash is integrated outside the package
Common peripheral interfaces such as MIPI-CSI, MIPI-DSI, USB 2.0 OTG HS, SDIO 3.0 TF card slot, dual microphones (supporting echo cancellation), speaker terminals and RTC battery terminals are brought out on the board
The board leads out 2 * 20 rows of sockets, leading out 28 remaining programmable GPIO interfaces
Security mechanisms: secure boot, flash encryption, hardware encryption accelerator, and hardware random number generator. Hardware access protection is also supported to implement access rights management (APM) and privilege separation
