ESP8266 Community Forum

- Thu Mar 12, 2020 12:23 am #86034 I am about to apply for european CE compliance testing with an ESP8266 product (lipo powered sensor, no mains) for the first time and I would like to prevent failing it and paying repeatedly Are there things that often fail in these tests and should be double checked? As I understand it it should pass these directives:

2014/30/EU - EMC

2014/35/EU - low voltage

2014/53/EU - Radio equipment

2011/65/EU - ROHS

Any advices will be highly appreciated

Also how do you guys protect your (commercial) ESP products against ESD and how do you test it yourselves before applying for compliance testing? I want to do ESD certification but I don't want to pay for the tests multiple times I found posts about using lighter piezo igniter for this but I am rather hesitant with that

You then have to show that your design follows the hardware design exactly as specified for the module, and that all software configurable settings have been applied as per the module compliance specs. Then you can supply the CE certificate for the module along with your design
