TM1637 4-digit 7-segment display (4-pin header)

tm1637GPIO

Why this support circuit is added

Bit-banged 2-wire (not I²C, no address). Any two digital pins; powering it from the MCU rail avoids level issues.

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.
