Reliable for Home Automation
Running ESPHome on this board without any issues. The processing power handles multiple sensors and MQTT traffic effortlessly. The built-in antenna works well even inside an enclosure.

Perfect for AI and Voice Projects
The N16R8 variant is a beast for running TinyML models. The extra PSRAM makes a huge difference when handling audio buffers for voice recognition projects. Setup with Arduino IDE was seamless.

Good hardware, steep learning curve
The board itself seems high quality, but as a beginner, I found the S3 architecture slightly different from the older ESP32 boards I used. Needed to update my drivers and libraries. Works great now though.

Best value for learning IoT
I bought this for my university final year project. The Bluetooth 5 LE range is impressive, and the Wi-Fi connection is stable. The price point for 16MB flash is unbeatable.

Excellent for Camera Projects
The camera interface support is robust. I connected an OV2640 module and the frame rates are smooth thanks to the octal PSRAM. Definitely the go-to board for visual AI applications.

Great board, minor documentation gaps
Hardware is solid and the dual USB ports are very convenient for debugging. However, finding specific pin mapping for the AI features took some digging in the GitHub repos. Otherwise, highly recommended.
Q: Does it come with a case or enclosure?
A: No, this product is the bare development board only. Enclosures are sold separately by third-party manufacturers. Please check our accessories section for compatible cases.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, you should not connect a LiPo battery directly to the 5V or 3.3V pins. Please use a dedicated LiPo charging module with a 5V output connected to the USB port or VIN pin, ensuring the voltage stays within the 5V limit.
Q: Is this compatible with the Arduino IDE?
A: Absolutely. You can install the ESP32 board package by Espressif Systems in the Arduino IDE Board Manager. Make sure to select 'ESP32S3 Dev Module' after installation.
Q: Does this board support external antennas?
A: Yes, the ESP32-S3-DevKitC-1 includes an IPEX connector for attaching an external antenna if you need extended range beyond the onboard PCB antenna.
Q: What is the difference between this and the ESP32-C3?
A: The ESP32-S3 features a dual-core Xtensa LX7 processor and supports Wi-Fi plus Bluetooth 5 LE, whereas the ESP32-C3 is a single-core RISC-V chip with similar connectivity but less processing power and no PSRAM options like the N16R8 configuration.
