Available Options
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.

i picked this up for a home automation project i'm working on, something to control lights and display info in a sleek way. as someone who loves tinkering and learning new tech, this board has been a fun challenge. the screen is the star—it's circular, which adds a cool futuristic vibe, and the resolution is so high that everything looks crisp. i used it to build a small dashboard for my kitchen, and it handles multiple touches without issues, making it interactive. under the hood, it processes images and voice pretty fast, which was key for my voice command integration. i connected a camera easily, and the memory hasn't been a problem even with more complex apps. on the downside, it wasn't cheap, and i had to spend a weekend getting everything configured properly. it does warm up a bit when i push it hard, but nothing too worrisome. overall, it's very capable and has met most of my needs, though it might be overkill for simpler projects. i'd recommend it to others who are into embedded systems and don't mind a learning curve :)
- Pros: the circular screen is very sharp and clear, making visuals pop from almost any angle, which is great for my projects. it's built like a tank, handling image and voice tasks smoothly without lag, and the touch response is accurate with support for multiple points. connectivity options are plentiful, allowing easy hookups to cameras and other gadgets, and the security features give me peace of mind for sensitive applications.
- Cons: the price was a bit high for my budget, even though i'm a deal hunter, and setting it up took some time due to the complexity. it can get warm during heavy use, which might be a concern for long sessions, and the documentation could be more beginner-friendly, as i had to rely on online communities for help.
