Notes:
nReset- Module hardware reset signal. Input. Logics “0” effective. There is a pull-up resister internal and no external pull-up is required. If needs reset, set low at least 10ms abd then set high. nLink- Module WIFI connection status indication. Output. (This pin is recommended to connect to LED, indicate status when the module in wireless upgrade mode) When the module connects to AP (AP associated), this pin will output “0”. This signal is used to judge if the module is already at WiFi connection status. Thers is a pull-up resister internal and no external pull-up required. If nLink function not required, can leave this pin open. nReady- Module boot-up ready signal. Output. Logics “0” effective. The module will output “0” after normal boot up. This signal used to judge if the module finish boot up and ready for application or working at normal mode. If nReady function not required, can leave this pin open. nReload- Module restored to factory default configuration.Input. Logics “0” effective. (This pin is recommended to connect to the button, is used to enter wireless upgrade mode) User can de-assert nReload signal “0” more than 4s through button or MCU pin, then release, module will restore to factory default configuration and re-start boot up process. If nReload function not required, can leave this pin open. UART0_TXD/RXD- UART port data transmit and receive signal.

NOTE: 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. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and operated with a minimum distance between 20cm the radiator your body: Use only the supplied antenna.
Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID 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 FCC ID: 2A4FR- MW-4E”
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01
