# Wireless Regulatory Notice

**This device incorporates an ESP32-S3-PICO-1 wireless module that transmits in the 2.4 GHz ISM band, making it an intentional radiator under radio-frequency regulations worldwide (including FCC Part 15 Subpart C in the United States, and the Radio Equipment Directive 2014/53/EU in the European Union).**

Although the ESP32-S3-PICO-1 module itself carries pre-existing regulatory certifications (FCC, CE, and others), those module-level certifications **do not automatically extend to a finished product** that incorporates the module. The pre-certified module exemption permits **individual hobbyists** to build a limited number of devices for **personal, experimental, or educational use** without obtaining separate equipment authorisation.

## Important Limitations

- Assembled devices **must not be sold, offered for sale, gifted, or otherwise distributed** to third parties unless the finished product has been independently tested and granted its own equipment authorisation (e.g. FCC ID, CE marking with a Notified Body assessment) in the relevant jurisdiction.
- Building this project for personal use in limited quantities is generally permitted under hobbyist and experimental-use provisions (e.g. FCC §15.23), provided the device does not cause harmful interference.
- Regulatory requirements vary by country. Builders outside the United States should consult their national radio-frequency authority for applicable rules.

## Builder's Responsibility

It is the builder's sole responsibility to ensure that any device constructed from these designs complies with all applicable radio-frequency regulations in their jurisdiction. The author provides these designs for personal, educational, and hobbyist use and makes no representation that a device built from them satisfies the regulatory requirements for commercial distribution.
