When it comes to certifications for the modules that go into another finished product, there are three options. Pre-certified, non-certified, or proprietary modules (modules you make on your own from scratch).
Pre-certified or certified modules, like those made by Thales, ensure that the module is ready to be used in another product. Depending on the design of the product or scheme, the module may not require much configuration.
More importantly, it means that the module meets the industry regulations. For instance, certified RF modules may meet the requirements of the Federal Communications Commission (FCC); the Innovation, Science, and Economic Development (ISED); and the European Conformity (CE).
On the other hand, a non-certified module does not guarantee compliance with industry standards or legal frameworks. This can be problematic in some cases. That’s not to say that it won’t work properly, but that it’s not approved or certified by a regulatory body.
In regions where such certifications are necessary, the finished product with a non-certified module may not get the certification or approval in that particular market. In such a case, you may have to get another lab or organization to certify the product.
However, non-certified modules are cheaper than certified modules because the manufacturer hasn’t spent the money on certifications.
