Ideal for Learning Embedded AI
I bought this for a university project on edge computing. The performance is surprising for the price point. The touchscreen library examples worked out of the box with Arduino IDE.

Best Value ESP32-S3 Board
Having the screen and mics integrated saves so much wiring time. The build quality feels premium, and the USB-C port is a nice touch. It boots up quickly and handles graphics well.

Exceeded Expectations
The color reproduction on the IPS screen is fantastic. I'm using it for a smart home control panel, and the UI looks professional. The microphone sensitivity is adjustable and works great.

Solid Performance
We are using these boards for our student robotics kits. They are robust and the Wi-Fi connection is stable. The only minor issue is that the speaker output volume could be slightly louder.

Perfect for Voice AI Projects
The dual microphone array works flawlessly with the XiaoZhi AI support. I was able to set up a voice assistant prototype in just a few hours. The screen is bright and responsive.

Great Hardware, Documentation Could Be Better
The board itself is excellent quality. The capacitive touch is very smooth. However, finding specific pinout diagrams for the microphones took some digging in the wiki. Overall, highly recommended for experienced users.
Q: Does this board support MicroPython?
A: Yes, the ESP32-S3 chip fully supports MicroPython. You can flash the firmware via USB and start coding immediately.
Q: Does it come with a case or enclosure?
A: No, the package includes only the development board and a USB-C cable. Cases are sold separately or can be 3D printed using files found online.
Q: Is the touchscreen resistive or capacitive?
A: This model features a capacitive touchscreen, which offers better clarity and multi-touch support compared to resistive screens.
Q: Can I power this with a 3.7V LiPo battery directly?
A: Absolutely. There is a dedicated JST connector on the board specifically designed for 3.7V LiPo batteries, and it includes charging circuitry via USB-C.
Q: What libraries are needed for the dual microphones?
A: You can use the standard ESP-IDF I2S drivers or specific Waveshare example codes available on their GitHub repository to access the dual microphone array.
