Issue: If cutting the end rows for the mini, the PCB will become unusable.
Fix TRRS connector
Issue: The current TRRS connector ST-0277D00-052-142 is not in stock and there are no compatible parts.
Alternative parts (You can choose any of them)
PJ-398A-5A: Very similar parts to current parts. It does not need to be modified on the case side but the circuit and firmware need to be modified to support TRS and it's not available at jlcpcb.
PJ-399B-6A: Very similar parts to current parts. The connector tip is long and needs to be modified on the case side and the circuit and firmware need to be modified to support TRS. -> to be default for jlcpcb files.
SJ-3501-SMT-TR: Compatible with PJ-399B-6A but the circuit and firmware need to be modified to support TRS.
