Supported radio revisions
| Exact board | Modeled LoRa ports | Frequency evidence |
|---|---|---|
| Seeed Wio-E5 mini v1.0 (HF) | SMA female socket; I-PEX (series not specified) | 868 / 915 MHz documented; other exact frequencies unverified |
| Seeed Wio-E5 Development Board v1.0 (HF) | SMA female socket; I-PEX (series not specified) | 868 / 915 MHz documented; other exact frequencies unverified |
| Heltec WiFi LoRa 32 V3.2 (863-928 MHz HF) | U.FL / IPEX1.0 board socket | 863-928 MHz HF variant |
The Wio-E5 pages link v1.0 board resources. SMA female mating is inferred from the manufacturer's explicit recommendation of SMA male antennas. IPEX subseries are not inferred. The Heltec entry is V3.2 HF only and does not cover V3.0, V3.1, V4 or LF variants.

How missing evidence behaves
Missing numeric cable ratings, an unspecified I-PEX series, undocumented antenna connectors and unsupported frequencies produce unknown findings. A known mismatch produces an incompatible overall result even when another finding is unknown. Nominal-only values do not become invented ranges.
Changing hardware specifications, seller substitutions and later revisions can invalidate a saved decision. Follow the references and confirm the exact ordered parts before buying. These links have no affiliate codes. No manufacturer endorsement or approval is claimed.
