- Remove the JTAG header and nets.
- Keep Reset/Boot; add a PTT momentary button on GPIO23 with ~10 k pull-up and small debounce cap.
- Rewire I2S: BCLK->GPIO18, WS->GPIO22, MIC_SD->GPIO16, AMP_DIN->GPIO20; relabel nets.
- Verify EN pull-up + cap and CP2102N auto-boot; run ERC and update BOM.

# Goal
- Update the ESP32-C6-MINI-1 smart-glasses schematic to match the new user GPIO mapping by removing the JTAG header, adding a new push-to-talk button on GPIO23, and reassigning the I2S nets while retaining the existing Reset (EN) and Boot (IO0) buttons. Ensure the schematic passes ERC, maintains CP2102N auto-boot support, and includes proper design practices for EN pull-up and noise immunity.
# Implementation plan
1. Update the schematic components:
1. Remove the JTAG header (J2) and disconnect all related JTAG nets.
2. Retain the Reset (EN) and Boot (IO0) buttons (S1, S2).
3. Add a new momentary push-to-talk (PTT) button assigned to GPIO23 with an appropriate pull-up resistor (~10k) and a small debounce capacitor to ensure noise immunity.
2. Reassign I2S nets connections on the ESP32-C6-MINI-1 (U1):
1. Connect I2S_BCLK from ESP32-C6-MINI-1 to GPIO18.
2. Connect I2S_WS from ESP32-C6-MINI-1 to GPIO22.
3. Connect MIC_SD from ESP32-C6-MINI-1 to GPIO16.
4. Connect AMP_DIN from ESP32-C6-MINI-1 to GPIO20.
5. Update net labels accordingly.
3. Verify supporting connections and components:
1. Confirm the EN pin’s pull-up resistor and noise-reducing capacitor are correctly implemented.
2. Ensure the CP2102N (U3) DTR/RTS connections for auto-boot are correctly routed to EN/IO0 on the ESP32-C6-MINI-1.
4. Run Electrical Rules Check (ERC) and update the Bill Of Materials (BOM) to include the added PTT button.
# Success criteria
- The JTAG header (J2) is completely removed from the schematic.
- A new push-to-talk button is added on GPIO23 with proper pull-up and debounce network.
- I2S nets are reassigned correctly to GPIO18, GPIO22, GPIO16, and GPIO20.
- The schematic passes ERC and all warnings have been addressed.
- The BOM is updated to include the new push-to-talk button component.
