Why this support circuit is added
3.3 V only (VDD 1.71–3.6 V): fed from the 3.3 V rail; the module carries its own pull-ups. Address 0x76 (0x77 with SDO high).
Grounded in the catalog and golden patterns (real open-source circuits). Every auto-inserted part comes with a reason.
Support circuit added automatically0
No extra support circuit for this part — only the board rail and the connector are wired.
