 Certification Information

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. Firmware version: V1.0 Test Antenna: Antenna 1(BLE Antenna): Internal Antenna and maximum gain 2.23dBi, Antenna 2(LoRa Antenna): External rod antenna and maximum gain 3.0dBi 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 a 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 301489, 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 that leads through a PC8 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 trade 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.
