Check the chain, then choose the parts.

An antenna name is not enough. The useful question is whether your exact radio port, every cable end and the antenna match at your intended frequency.

Start with the hardware you have

Read the board marking and your order record together. A product family name may cover several revisions and frequency variants. In MeshMatch, a listed revision refers to the unmodified board in the cited manufacturer documentation. A different enclosure, added pigtail or replacement antenna can change the exposed connection.

The catalog currently covers Wio-E5 mini v1.0, Wio-E5 Development Board v1.0 and Heltec WiFi LoRa 32 V3.2 HF. It is deliberately small. Choose another model only when it is the board you actually have. If your board is absent, use the checking method here and consult its manufacturer rather than treating a similar name as equivalent.

Follow a repeatable sequence

1. Record the complete board revision and HF or LF variant. Keep a photo of its markings for your own records.
2. Identify the LoRa antenna port. A connector elsewhere on the device may serve a different radio.
3. List the connectors in their physical order, from the radio outward. Include a case-mounted pigtail.
4. Find a numeric frequency range for the antenna and cable. A nominal frequency does not establish bandwidth.
5. Run the check with your intended channel frequency in MHz and read every finding.
6. Export the parts list as a new JSON file. It preserves the selected parts, uncertainty and source links for review.

Read the result as a specification decision

Compatible means all modeled connector and frequency checks are supported. Incompatible means at least one known mismatch blocks the chain, even when other details are unknown. Unknown means the available evidence does not settle the whole chain. Unknown does not mean nearly compatible.

The manufacturer selection guide supports direct SMA antenna choices for the Wio-E5 boards. The I-PEX cable listing does not identify every mating series or provide a numeric RF rating, so cross-device cable chains retain uncertainty. MeshMatch reports that gap rather than converting a generic connector name into a guarantee.

• Trace connectors without guessing

  SMA, RP-SMA, I-PEX and why the exposed enclosure port matters.

• Read frequency coverage carefully

  Band edges, nominal values and the difference between hardware coverage and permission to transmit.

• Build a useful pre-purchase parts record

  Resolve unknowns with a supplier and preserve the evidence alongside your choices.

• Work through compatible, incompatible and unknown examples

  Three reproducible selections, the findings they produce and what to do next.
