Wireless-Tag Technology Co., Ltd. V1.0.0 3.3 Strapping Pins ESP32-S3 series has four strapping pins. GPIO0 = IO0 GPIO45 = IO45 GPIO46 = IO46 GPIO3=IO3 Software can read the strapping values of these pins in the register "GPIO_STRAPPING". During the system reset of the chip (power-on reset, RTC watchdog reset, brown-out reset, analog super watchdog reset, crystal oscillator clock glitch detection reset), the Strapping pin has the same function as the one on its own pin.

Federal Communication Commission Statement (FCC, U.S.) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End product labeling: The final end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2AFOS-WT32S3WROVERX”.
integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. 2.4 Limited module procedures Not applicable. 2.5 Trace antenna designs Not applicable. The module has its own antenna, and doesn’ t need a host’ s printed board microstrip trace antenna etc. 2.
WIFI Operation Frequency: 2412~2462MHz Number of Channel: 11 Modulation: DSSS, OFDM Host manufacturer must perfom test of radiated & conducted emission and spurious emission, etc according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. Only when all the test results of test modes comply with FCC requirements, then the end product can be sold legally. 2.
