This document is a request to the FCC (Federal Communications Commission) to change the identification of a previously approved device. The University of Chicago is applying for a new FCC ID (2BGQ4-TMWCTW47) for a device that was originally certified under the FCC ID 2AC7Z-ESP32WROOM32E by ESPRESSIF SYSTEMS (SHANGHAI) CO.
The request is made according to 47 CFR 2.933(b), which allows for a change of identification under certain conditions. The University of Chicago confirms that the equipment is electrically identical to the originally approved device. The only changes are the model name, trade name, and FCC ID number. The original test results remain applicable and representative of the device's performance.
The application includes a cover letter, external photos, and information about the FCC ID label format and location. The original grant date for the device was April 10, 2022.
