Replaced my old ESP8266 projects
The upgrade in processing power and memory is noticeable. I migrated my home automation nodes to these S3 boards and they handle MQTT and local logic much better without lagging.

Great performance, minor pinout quirks
The ESP32-S3 chip on this matrix board is powerful. I love the extra RAM for running TensorFlow Lite models. Just be sure to check the pinout diagram carefully as some pins are shared with the flash interface.

Excellent for computer vision prototypes
I am using this with a small camera module for object detection. The vector instructions really speed up the inference time. It runs cool even under load. Very satisfied with this purchase.

Perfect for AI Voice Projects
This board is exactly what I needed for my XiaoZhi AI assistant project. The PSRAM handles the audio processing smoothly, and the native USB makes debugging incredibly fast. Highly recommended for anyone getting into edge AI.

Solid board, fast shipping
Works out of the box with Arduino IDE after installing the ESP32 board manager. The only reason for 4 stars is that the documentation could be slightly more detailed regarding power consumption modes.

Best value for learning IoT
Bought this for my university final year project. It connects to Wi-Fi instantly and the community support for ESP-IDF is huge. The build quality feels solid and the headers are well-soldered.
Q: Does it come with a case or enclosure?
A: No, this listing is for the core development board only. Enclosures are sold separately. Please check our accessories section for compatible acrylic or 3D printable case designs.
Q: Does this board support MicroPython out of the box?
A: Yes, the ESP32-S3 is fully compatible with MicroPython. You will need to flash the latest MicroPython firmware binary via the USB interface to get started.
Q: Can I power this board directly via the 5V pin?
A: It is recommended to power the board via the USB-C port for stable operation. If using external power, please ensure it is regulated 5V and connected to the correct 5V/GND pins, avoiding the 3.3V pin to prevent damage.
Q: Is this board suitable for battery-powered projects?
A: Absolutely. The ESP32-S3 features advanced power management including deep sleep modes. You can connect a Li-Po battery using an external BMS or a dedicated power management shield designed for ESP32.
Q: What is the difference between the N8R8 and N16R8 versions?
A: The number before 'R' indicates the Flash memory size (8MB vs 16MB), and the number after 'R' indicates the PSRAM size (8MB). Both use the same ESP32-S3 chip, but the N16R8 offers more storage for larger applications.
