Perfect for compact IoT projects
The split-type design is genius. It allows me to embed the core module directly into my custom PCB while keeping the peripherals accessible during development. Wi-Fi connection is stable and the Bluetooth LE works flawlessly.

Great board, minor learning curve
Excellent performance and the dual-core processor handles multitasking well. The only reason for 4 stars is that the pinout diagram could be clearer for beginners, but once you figure it out, it's a powerhouse.

Reliable wireless connectivity
Been running this board for two weeks straight monitoring environmental sensors. The Wi-Fi reconnect logic is robust, and power consumption in deep sleep mode is incredibly low. Waveshare quality is consistent.

Easy to use with Arduino IDE
I was able to get this running with the Arduino IDE in under 10 minutes. The community support is huge, and the board recognizes instantly on my laptop via USB-C. Great value for money.

Solid performance for robotics
Using this for a small wheeled robot. The processing speed is sufficient for sensor fusion and motor control. The form factor saves a lot of space inside the chassis. Wish it had more GPIOs broken out directly.

Superior to standard ESP32 modules
The S3 chip offers significant improvements over the original ESP32, especially with the native USB support which eliminates the need for an external UART bridge. Highly recommended for professional prototyping.
Q: Can I power this board via the USB-C port?
A: Yes, the board can be powered directly through the USB-C port, which also provides data communication and programming capabilities.
Q: Does it support external antennas?
A: This specific Tiny model uses an onboard PCB antenna for compactness and does not have a connector for an external antenna.
Q: Does this board come with headers pre-soldered?
A: No, this is a split-type development board designed for flexibility. It typically comes without headers soldered so you can choose to solder them yourself or use the gold fingers to connect to a carrier board.
Q: Is this compatible with the ESP-IDF framework?
A: Absolutely. The ESP32-S3 chip is fully supported by the Espressif IoT Development Framework (ESP-IDF), along with Arduino IDE and MicroPython.
Q: What is the maximum current output for the 3.3V pin?
A: Please refer to the specific schematic in the wiki for precise limits, but generally, you should not draw more than 500mA total from the board's regulator to ensure stability.
