Best value for money
You get a lot of memory and processing power for the price. The build quality of the FireBeetle series is always top-notch. Will buy again.

Great upgrade from standard ESP32
I switched to the FireBeetle 2 for a new smart home hub. The native USB support simplifies the hardware design significantly. Highly recommended for professionals.

Reliable and Fast
Using this for a quadruped robot controller. The dual-core processor handles motor control and Wi-Fi telemetry without any lag. Very stable.

Solid performance
Works great with various sensors. The only minor issue is that some older libraries need updates to be fully compatible with the S3 architecture, but that's expected.

Perfect for AIoT Projects
The extra PSRAM on this board makes a huge difference for my image processing projects. The ESP32-S3 chip is fast and the USB-C connection is very convenient.

Good board, steep learning curve
Excellent hardware specs with 16MB flash. It took me a while to configure the Arduino IDE correctly for the S3 variant, but once running, it works flawlessly.
Q: Is there a battery charging circuit included on this board?
A: This specific model (ESP32-S3-U) does not include an onboard LiPo charging circuit. You will need an external charger module if you plan to use a battery.
Q: Can I use this board with the Arduino IDE?
A: Absolutely. Just install the ESP32 board package by Espressif Systems in your Arduino IDE preferences and select 'FireBeetle 2 ESP32-S3' or the generic 'ESP32S3 Dev Module'.
Q: What is the maximum current this board can supply to external sensors via the 3.3V pin?
A: We recommend drawing no more than 500mA total from the 3.3V regulator to ensure stability. For high-power devices, please use an external power source.
Q: Does the 8MB PSRAM come pre-soldered?
A: Yes, the N16R8 designation indicates that 16MB Flash and 8MB PSRAM are integrated and soldered onto the module. No additional components are needed.
Q: Does this board support MicroPython out of the box?
A: Yes, the ESP32-S3-U is fully compatible with MicroPython. You will need to flash the latest S3-specific firmware image to get started.
