Bluetooth 5 LE is a game changer

I am using this for a low-power sensor node. The Bluetooth 5 LE range and stability are impressive compared to older modules. Highly recommended for battery-operated projects.

Best value S3 board currently available

Compared to other vendors, Lvshen offers the best price-to-performance ratio. The octal PSRAM speed boost is noticeable when handling large data buffers.

Good for learning Edge AI

As a student, this board provides enough power to experiment with image recognition locally. Documentation could be better, but the community forums are very helpful.

Perfect for AIoT Projects

The 16MB flash and 8MB PSRAM make this board a beast for running TinyML models. Setup with Arduino IDE was seamless, and the native USB support simplifies debugging significantly.

Great specs, minor pinout confusion

Excellent performance for the price. The only downside is that the pinout differs slightly from the classic ESP32, so double-check your schematics before connecting peripherals.

5 FAQ

Q: Can I power this board via the USB-C port alone?

A: Absolutely. The board features a built-in LDO regulator that allows it to be powered directly through the USB-C port without an external power supply.

Q: Is the antenna external or internal?

A: This module comes with an onboard PCB antenna. However, there is a U.FL connector available on some variants if you require an external high-gain antenna.

Q: What is the maximum current draw for the 3.3V pin?

A: We recommend drawing no more than 50mA from the 3.3V pin for external sensors. For higher current requirements, please use an external regulated power source.

Q: Does it work with the ESP-IDF framework?

A: Yes, this board is officially supported by the Espressif IoT Development Framework (ESP-IDF). You can select the 'ESP32-S3' target in your project configuration.

Q: Does this board support MicroPython out of the box?

A: Yes, the ESP32-S3 chip is fully compatible with MicroPython. You will need to flash the latest firmware binary suitable for the N16R8 configuration.
