Perfect for AIoT Projects

This board works flawlessly with the XiaoZhi AI module. The N16R8 configuration provides plenty of memory for my voice recognition tasks. Setup was easy using the Arduino IDE.

Reliable Performance

We deployed several of these for prototyping. The PSRAM handling is excellent for buffering data. No overheating issues during prolonged tests.

Good Value

Solid board for the price. Documentation could be slightly more detailed for beginners, but community support fills the gap. Works as expected.

Fast and Efficient

The S3 chip is noticeably faster than the older ESP32 models. Flashing firmware is quick. Verified purchase and satisfied with the quality.

5 FAQ

Q: Is an external antenna included?

A: No, this model uses an onboard ceramic antenna. There is no connector for an external antenna on this specific variant.

Q: Can I power this via the 5V pin?

A: Yes, you can supply 5V to the 5V pin, but ensure the voltage is stable to prevent reset issues.

Q: What USB driver is required for Windows?

A: Depending on the production batch, it may use the CH343 or CP210x driver. Both are readily available online.

Q: Is this compatible with 5V logic sensors?

A: No, the GPIO pins operate at 3.3V logic levels. Please use level shifters for 5V devices to avoid damage.

Q: Does it support MicroPython out of the box?

A: The board hardware supports it, but you may need to flash the MicroPython firmware separately using a flashing tool.
