Solid connectivity
Wi-Fi and Bluetooth LE connection is very stable. I used it for a smart home sensor node and it has been running for weeks without disconnection issues.

Great specs, compact size
Love the form factor. It fits perfectly into my custom enclosures. Only minor issue is that some GPIO pins are shared with the flash, so check the pinout carefully before designing your PCB.

Best in class for S3
The N16R8 configuration is exactly what high-performance embedded projects need. The vector instructions really speed up matrix calculations for neural networks.

Perfect for AIoT Projects
The 16MB flash and 8MB PSRAM make this board a beast for running TinyML models. The native USB support simplifies debugging significantly compared to older ESP32 variants.

Good learning board
As a beginner, the documentation online is plentiful. The board works out of the box with the Arduino IDE. Took off one star because the silk screen printing is a bit small to read easily.

Excellent value for money
Switched from the standard ESP32 to this S3 version for the extra RAM. Compiling large Arduino sketches or MicroPython scripts is much smoother now. Highly recommended.
Q: Can I power this via the VIN pin instead of USB?
A: Yes, you can supply 5V to the VIN pin. Ensure the voltage stays within the 4.75V to 5.25V range to avoid damaging the onboard regulator.
Q: What is the maximum current this board can supply to peripherals?
A: The 3.3V regulator can typically supply up to 500mA, but we recommend keeping the load under 300mA for stability when using Wi-Fi heavily.
Q: Does this board support external antenna connections?
A: This specific NANO model features an onboard ceramic antenna. It does not have an IPEX connector for an external antenna.
Q: Is it compatible with MicroPython?
A: Yes, the ESP32-S3 chip is fully supported by MicroPython. You can find the latest firmware binaries on the official MicroPython website.
Q: Does it come with headers pre-soldered?
A: No, this board is shipped without headers to keep the profile low. You will need to solder your own male or female headers depending on your project needs.
