ESP32-C61 certifications: check the exact module before selecting hardware
Espressif's official records identify certifications for different ESP32-C61 modules. Learn how to organize this documentation when selecting hardware for IIoT and avoid conclusions that certificate titles do not support.

In short
Selecting a module for an IIoT project also involves checking its documentation. In the official records provided for this article, Espressif identifies certification documents for ESP32-C61-WROOM-1, ESP32-C61-WROOM-1U and ESP32-C61-MINI-1. The similarity of the names calls for care: a document reference must retain the full identification of the product it is associated with.
The aim here is to organize this review before choosing the hardware. The available information allows us to identify the records, but not to describe the contents of the certificates in detail. Accordingly, the recommendations below address document traceability, without attributing electrical characteristics, performance or functionality to the modules that these references do not describe.
What it is
Espressif lists the record “ESP32-C61-WROOM-1 WFA Certificate”, explicitly associated with ESP32-C61-WROOM-1. There is also a separate record, “ESP32-C61-WROOM-1U WFA Certification”, for the name with the U suffix.
Another document is listed as “ESP32-C61-WROOM-1 IC Certification”. The supplied list therefore contains two records with the name ESP32-C61-WROOM-1 and distinct certification labels: WFA and IC.
For ESP32-C61-MINI-1, the supplied record is “ESP32-C61-MINI-1 CE Certification”. This list describes only the documents selected as sources for this article. It does not represent a complete inventory of the certifications available for each module.
What it is for
As an engineering editorial practice, we recommend recording the full module name in the bill of materials and the selection documentation. A generic note such as “ESP32-C61 with certification” removes precisely the distinctions that appear in the source titles.
For each item under evaluation, keep the module identifier, document title and corresponding official URL together. If the selection changes from WROOM-1 to WROOM-1U or MINI-1, revisit the documentation review. The supplied titles do not establish equivalence between these variants or justify transferring conclusions from one to another.
This practice also makes it easier for someone else to review the selection: they can check which reference supported the choice without having to infer the variant from an abbreviated description.
Where it is used
Finding an official record is one step in the analysis. Determining its scope requires the contents of the document. Because the supplied data does not include the conditions of the certificates, this article makes no claims about countries where they are valid, integration restrictions, antenna configuration or requirements applicable to the final equipment.
For the same reason, do not use these titles as an automatic answer to a customer requirement. We recommend turning each requirement into a specific documentation question and recording which document actually answers it. When the title is insufficient to answer the question, the conclusion must remain limited to identifying the record.
Also avoid interpreting the absence of a particular document from this selection of sources as proof that certification is absent. The list is a subset, and it contains no statement of exhaustive coverage.
Relevance for industry
When selecting hardware for a project involving MQTT, Modbus, RS-485 or SCADA, organize the certification documentation separately from the application's functional requirements. This is a process recommendation: the cited titles do not present test results for these protocols or for integration with supervisory systems.
An evaluation sheet can record the proposed module, the official certification reference and the project requirements that still need their own supporting evidence. Do not fill in these requirements with inferences drawn from the acronyms WFA, IC or CE. The supplied sources also do not support figures for range, latency, stability or communication capacity.
Impact on embedded systems
Before approving the documentation for a variant, check that the name recorded in the specification matches the name in the reference used. Then review whether each certification claim is supported by the appropriate document and whether any conclusion has been extended to another module simply because it shares the ESP32-C61 prefix.
Limits and what is still missing
The expected outcome of this organization is a justifiable selection: precise hardware identification, official references that can be located and clear limits on what the documentation reviewed allows you to claim.
