Frequently Asked Questions
How do I program the ShillehTek ESP32-S3-Nano using Arduino IDE?
Install ESP32 board support in Arduino IDE, select the appropriate ESP32-S3 board/port, then upload over USB. If uploads fail, re-check the selected board profile and USB cable/data connection.
Can I use ESP-IDF with this ESP32-S3 Nano dev board?
Yes. The board is compatible with common ESP32 workflows such as ESP-IDF; choose an ESP32-S3 target and confirm pin mappings using the board silkscreen and listing photos.
Where can I find the ESP32-S3-Nano pinout for wiring sensors and peripherals?
Use the silkscreen labels printed on the board and the product listing photos for the exact pin names. Pin assignments can vary between revisions, so avoid relying on generic pinout images.
Is this board good for WiFi + BLE IoT sensor nodes and smart home projects?
Yes. The onboard WiFi and Bluetooth Low Energy (BLE), plus the small footprint and presoldered headers, make it well-suited for connected prototypes like sensor nodes, remote controls, and telemetry devices.
