Good but docs lacking

Hardware is solid, but the pinout diagram in the box was hard to read. Had to find it online.

Great board, minor pin issue

Performance is excellent. Wish the pin headers were pre-soldered as I had to buy them separately.

Perfect for IoT Projects

Works straight out of the box. The driver-free feature saved me a lot of hassle on Windows. Highly recommend for beginners.

5 FAQ

Q: Does this support 5V logic levels on GPIO?

A: No, the GPIO pins operate at 3.3V logic levels. Using 5V directly may damage the board.

Q: Does it come with pre-soldered headers?

A: This minimal version does not include pre-soldered pin headers to keep the profile low.

Q: What is the deep sleep current consumption?

A: Typically around 13uA in deep sleep mode depending on your specific configuration and peripherals.

Q: Can I use this with Arduino IDE?

A: Yes, it is fully compatible with the Arduino IDE using the ESP32 board manager package.

Q: Is the PSRAM usable for graphics buffers?

A: Yes, the 8MB PSRAM is excellent for LCD buffers, audio processing, and AI model storage.
