Excellent IoT solution
Low power consumption in deep sleep mode. Great value for the price compared to other S3 boards on the market.

Decent but tricky pinout
Needed a breakout adapter to use with my breadboard. The board itself works, but the small form factor is not beginner-friendly.

Perfect for wearables
Compact and powerful. The size makes it ideal for my smartwatch project. Wi-Fi connection is stable and the USB-C port is a nice touch.

Fast delivery, works out of the box
Uploaded code via Arduino IDE without any drivers issues. Bluetooth pairing was quick. Highly recommend for embedded projects.

Good board, minor docs issue
Works well for IoT sensors. Had some trouble finding the exact pinout diagram initially, but once configured, it runs smoothly.
Q: What is the logic voltage level for the GPIO pins?
A: The GPIO pins operate at 3.3V logic level. Please ensure connected sensors are compatible or use level shifters.
Q: Is this board compatible with the Arduino IDE?
A: Yes, it is fully compatible. You can install the ESP32 board package in Arduino IDE to start programming.
Q: Does it support external antennas?
A: This model uses an onboard PCB antenna. For external antenna options, please check our ESP32-S3 variants with IPEX connectors.
Q: What is the current consumption in deep sleep mode?
A: Typical deep sleep current is approximately 15uA, depending on peripheral configuration and PSRAM state.
Q: Can I connect a LiPo battery directly to this board?
A: No, this board does not have a built-in charging circuit. Please use an external battery management module.
