ESP32-P4 3.4" Round Touch Display Dev Board (800x800)

This Waveshare display development board is built around the ESP32-P4, with a dual-core plus single-core RISC-V setup. It has a 3.4" round IPS touch display with an 800×800 resolution, and is aimed at embedded projects that need strong human-machine interface support, edge computing capability and plenty of IO. The display is a 3.4" round IPS toughened glass panel with 10-point touch, 170° viewing angles and 300cd/m² brightness. The board uses a RISC-V 32-bit dual-core high-performance (HP) system with DSP, instruction set expansion, an FPU and speeds up to 360MHz, alongside a RISC-V 32-bit single-core low-power (LP) system running at up to 40MHz. It also includes an ESP32-C6 co-processor, adding Wi-Fi 6, Bluetooth 5 and related functions over SDIO. Memory includes 128 KB HP ROM, 16 KB LP ROM, 768 KB HP L2 memory, 32 KB LP SRAM, 8 KB system TCM (Tightly Coupled Memory), 32 MB PSRAM stacked in the package, and 32MB Nor Flash connected over QSPI. The board features a USB-A USB 2.0 OTG interface, SDIO3.0 MicroSD card slot, USB-C UART flashing port, 40-pin GPIO expansion interface (compatible with some Raspberry Pi HATs). It also has an onboard speaker interface and dual microphones, supported by a codec and power amplifier. An RTC chip and RTC battery header (compatible with the RTC Battery for Pi 5), provides real-time clock functions. There is an onboard MIPI-CSI high-definition camera interface with support for full HD 1080P image capture and encoding, an integrated ISP, and H.264 and JPEG video encoding at 1080P @30fps. It also includes a MIPI-DSI high-definition display interface, integrated PPA (Pixel Processing Accelerator), 2D DMA (Direct Memory Access), and JPEG image decoding at 1080P @30fps. The display comes with a speaker unit and 4-pin UART/I2C cable. Features
