BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
| Parameter | Suggested range or common values | Where it comes from |
|---|---|---|
| Rate (Mbps)Decisive | 0.25 to 50 Mbps | Redefined here |
| DuplexDecisive | Half duplexFull duplex | This category's own |
| NodesImportant | 32 to 256 | This category's own |
| Supply voltage (V)Important | 3 to 5.5 V3.35 | Redefined here |
| IsolationImportant | Yes / no | Redefined here |
