Round LCD Touch Screen Development Board
ESP32-P4 based 4-inch round screen development board


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 4-inch 720 × 720 resolution IPS circular touch screen; it 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.
