Waveshare ESP32-P4 Touch Circular LCD Screen Development Board: High-performance dual-core RISC-V processor
There's a task: build a slick, interactive gadget. Here's the button: the WAVESHARE ESP32-P4 Touch Circular LCD Screen Development Board. This isn't your average dev board—it's a powerhouse wrapped in a 3.4-inch circular display with an 800x800 resolution. Think crisp visuals from almost any angle, thanks to that 170-degree ultra-wide view, plus a high 1200:1 contrast and 10-point touch support. Perfect for anything from smart mirrors to futuristic control panels.
Under the hood, an ESP32-P4 module with a RISC-V 32-bit dual-core processor handles the heavy lifting. It's built for image and voice processing, chewing through JPEG encoding/decoding, image signal tasks, and even 264 video encoding without breaking a sweat. With 32MB of PSRAM and 32MB Nor Flash, memory isn't a bottleneck for complex apps.
Connectivity? It's got the goods: MIPI-CSI and DSI for cameras and displays, USB 2.0 OTG HS for peripherals, SDIO 3.0 for TF cards, dual mics with echo cancellation, and speaker terminals. Security features like secure boot, Flash encryption, and a hardware random number generator keep things locked down. Ideal for indoor monitoring, digital dashboards, or AI-driven projects, this board integrates everything for responsive, efficient systems. Support for mainstream AI and online models? Check. It's the Swiss Army knife for embedded tinkerers.
