Conformity Assessment of the Radio Module to

the RED

This radio module is for professional installation only. When installing this radio module permanently

into a host product to a create new radio equipment device; the manufacturer responsible for placing

the final radio product on the market in the EU must assess if the combination of this radio module

and the host product complies with the essential requirements of the RE Directive 2014/53/EU.

Software version：V150

Test Antenna: Antenna type External fixed rubber antenna, WIFI 2.4GHz band Peak Gain 2.33(dBi),

BT/BLE Peak Gain 2.33(dBi).

The final radio product will need to be fully assessed to Article 3.1a of the RED, for product safety

With regard to RF exposure for Article 3.1a of the RED, the manufacturer of the final radio product

will need to assess if the compliance assessment of the original radio equipment/module remains

relevant to the final radio product, or if further action is necessary.

This equipment should be installed and operated with minimum distance 20cm between the

radiator& your body.

If the final radio equipment is used at the same distance from a person or domesticated animal as the

radio module was assessed, (for example: >20cm), then the final radio product assessment could

conclude that the final radio product is compliant with the RF exposure requirements without

additional actions.

If the final radio equipment is used at a closer distance from a person or domesticated animal than

the radio module was assessed, then the final radio product assessment could not automatically

conclude that the final radio product is compliant with the RF exposure requirements without

additional actions; and further assessment is necessary.

The final radio product will need to be fully assessed to Article 3.1b of the RED, for EMC.

EMC testing of the radio module will have been performed on some sort of temporary host or test jig;

but now the module is in a new host product and the EMC performance of the final radio product

must be assessed.

Most likely the host product will have its own EMC assessment for other functions, which should be

performed with the radio module installed; and inclusion of the radio module into the host product

will also require an assessment, such as to the relevant applicable part of EN 301 489, on the final

radio product.

In theory, radio transmitter or receiver measurements made as conducted measurements at a radio

module antenna port may be considered applicable to the radio performance of the final radio

product. However, in this example, the radio module does not have an antenna port. The radio

module has a pin which leads through a PCB trace to an antenna on the host product. If the

manufacturer of the final radio product wishes to use conducted power, conducted emissions or

receiver performance measurements from the radio module to show compliance of the final radio

product, then they will need to exactly follow the detailed instructions from the radio module

manufacturer; including input voltage, driver software, environmental conditions, antenna trace

layout design construction and material, circuit board layout design construction and material,

nearby circuitry, etc. In reality, it is expected that manufacturers of final radio products will need to

test the output power, conducted spurious emissions and receiver performance requirements on the

final radio product; and not take the results of those test cases from the radio module test reports.

Radiated test cases will also need to be performed on the final radio product.
