⚙️ First-Time Setup (Important – Read Before Use)

If your board repeatedly disconnects and reconnects when first plugged in, follow these steps:

1. Before connecting to your computer, use a jumper or short wire to bridge pin header "B1" to "GND".
2. Connect the board to your computer via a USB cable.
3. Once the computer recognizes the device, remove the wire between "B1" and "GND".
4. The board is now ready for normal operation and programming.

Frequently Asked Questions

Q: What is the ESP32-S3 Nano Development Board and what can I build with it?

A: The ESP32-S3 Nano is a compact, Arduino-compatible microcontroller development board featuring 16MB of flash memory, 2.4GHz WiFi, and dual-mode Bluetooth. It's ideal for IoT projects, home automation, wearable tech, sensor nodes, and any project requiring wireless connectivity in a small form factor.

Q: Why does the board keep disconnecting and reconnecting when I plug it in for the first time?

A: This is a known first-time setup behavior. Before plugging in the USB cable, bridge pin header "B1" to "GND" with a jumper or short wire. Connect the board to your computer, wait for it to be recognized, then remove the jumper. The board will then operate normally for all subsequent connections.

Q: Is this board compatible with the Arduino IDE?

A: Yes. The ESP32-S3 Nano is fully compatible with the Arduino IDE. Simply add the ESP32 board package to your IDE, select the appropriate board profile, and you're ready to upload sketches using standard Arduino workflows. It also supports Espressif's ESP-IDF framework for more advanced development.

Q: How many units can I order at once?

A: This listing offers flexible quantity options — you can order 1pc, 2pcs, 3pcs, 5pcs, or 10pcs to suit individual prototyping needs or small-batch production runs.
