Fast and Reliable
Compilation times are fast, and the dual-core performance handles multitasking smoothly. I used it for a smart camera project and the image processing speed was impressive.

Perfect for AIoT Projects
The native USB support on this S3 board makes debugging so much easier compared to older ESP32 models. The extra PSRAM is a game changer for running TinyML models.

Solid upgrade from ESP32-C3
The additional IO matrix flexibility is welcome. Only giving 4 stars because the onboard LED is a bit dim, but that's a trivial issue for a dev board.

Great board, minor pinout confusion
Hardware is solid and Wi-Fi range is excellent. Just be careful checking the specific pinout for your variant (N8R2 vs N16R8) as some strapping pins differ slightly from the standard ESP32.

Excellent for motor control
We integrated this into our prototype robot controller. The PWM resolution and timer capabilities are superior, allowing for very smooth servo control.

Best learning board currently available
As a student, the compatibility with both Arduino and ESP-IDF is crucial. This board works out of the box with no driver issues on Windows 11.
Q: Does this come with pre-installed firmware?
A: The board typically comes with a basic factory test demo. You will need to flash your own firmware using ESP-IDF, Arduino IDE, or a UF2 bootloader for drag-and-drop programming.
Q: What is the difference between the N8R2 and N16R8 versions?
A: N8R2 has 8MB of Flash and 2MB of PSRAM. N16R8 has 16MB of Flash and 8MB of PSRAM. Choose based on your storage and memory requirements.
Q: Is the USB port capable of acting as a host for keyboards or mice?
A: Yes, the ESP32-S3 features native USB OTG (On-The-Go), allowing it to act as a host to connect peripherals like keyboards, mice, or MIDI devices.
Q: Can I power this board directly with a 5V battery pack?
A: Yes, you can supply 5V through the VIN pin or the USB-C port. The onboard regulator will step it down to 3.3V for the chip.
Q: Does this board support 5GHz Wi-Fi networks?
A: No, the ESP32-S3 chip only supports 2.4GHz Wi-Fi (802.11b/g/n). It does not support 5GHz bands.
