INTEGRATION INSTRUCTIONS

FCC rules

The ESP32-SL is an WIFI+BT Module Module with frequency hopping using an ASK modulation. It

operates on the 2400 ~2500 MHz band and, therefore, is within U.S. FCC part 15.247 standard.

Modular installation instruction

1,ESP32-SL Integrates high-speed GPIO and peripheral interface. Please pay attention to the

installation direction (pin direction).

2,Antenna could not be in no-load state when module is working. During debugging, it is suggested

to add 50 ohms load to the antenna port to avoid damage or performance degradation of the module

under long-time no-load condition.

3,When the module needs to output 31dBm or more power, it needs a voltage supply of 5.0V or

more to achieve the expected output power.

4,When working at full load, it is recommended that the entire bottom surface of the module be

attached to the housing or heat dissipation plate, and it is not recommended to conduct heat

dissipation through air or screw column heat conduction.

5,UART1 and UART2 are serial ports with the same priority. The port which receives commands

returns information.

RF exposure considerations

To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed

and operated with minimum distance between 20cm the radiator your body: Use only the supplied

antenna.

Antennas

The ESP32-SL is an UHF RFID Module beams signals and communicates with its antenna, which is

Panel Antenna.

LABEL OF THE END PRODUCT

The final end product must be labeled in a visible area with the following：

Host must Contains FCC ID: 2ATPO-ESP32-SL. If the size of the end product is larger than

8x10cm, then the following FCC part 15.19 statement has to also be available on the label: This

device complies with Part 15 of FCC rules. Operation is subject to the following two conditions:

(1) this device may not cause harmful interference and

(2) this device must accept any interference received, including interference that may cause

undesired operation.
