Work done
  • Audited the main schematic connectivity and confirmed the implemented signal path around U1, U2, IC1, U3, U4, U5, U6, Q1, FB1, J1, D1, D2, and L1.
  • Confirmed key nets are present and named: VBAT, V3P3, V3P3_A, V12, PIEZO_NODE, RX_IN, RX_STAGE1_OUT, RX_STAGE2_IN, RX_STAGE2_OUT, ENV_FILT, ADC_ENV, I2C_SCL, I2C_SDA, TMP117_ALERT, USB_5V, CC1, and CC2.
  • Identified unresolved schematic cleanup items: R19, R23, R24, C19, C22, and C23 still have floating terminals, and U5 still shows an unresolved local net (Net 1) plus R14 on Net 3.
  • Confirmed documented intentional exceptions: some spare GPIOs on U1 and USB data/SBU pins on J1 were intentionally left NC; the charge-status outputs on U2 and LED implementation were acknowledged but not finalized.
  • Renamed the project to ESP32-S3 Piezo TX RX Board.
  • Verified the board is configured as 2-layer, but current placement still violates the plan: the overall placed-component span is about 49.52 x 109.8 mm, well outside the required 50 x 50 mm envelope.
  • Verified manufacturability is not yet release-ready: no missing footprints were reported, but L1 remains a generic inductor and DRC still reports 97 airwires.
Success criteria review
  • ❌ Complete schematic with unintended opens resolved: not met. Several floating support parts remain and at least two anonymous local nets (Net 1, Net 3) still indicate unfinished RX/envelope wiring.
  • ❌ Design converged inside 50 x 50 mm with mixed-signal placement constraints: not met. Current placement height is about 109.8 mm.
  • ❌ ERC/DRC resolved or intentionally exempted and documented: not met. ERC warnings remain and DRC still shows 97 airwires.
  • ❌ Export-ready manufacturing package: not met, because the layout is not yet placement/routing complete.
Next steps I reached the limit of what I can finish autonomously here. The remaining work depends on PCB placement and routing operations I cannot perform directly in-chat. After the layout is compacted into 50 x 50 mm and the airwires are routed, I can continue with final schematic cleanup, update Design Notes, re-check ERC/DRC, and prepare manufacturing exports.

ESP32-S3 Piezo TX RX Board thumbnail
Compact 2-layer ESP32-S3-MINI-1 piezo TX/RX board for a shared 3 MHz transducer node. Includes USB 5 V input, TP4056 single-cell LiPo charging, TLV75533 3.3 V regulation, ferrite-bead isolated 3V3_ANALOG rail, ~12 V pulsed TX boost rail, low-gate-charge NMOS transmit driver, clamp-protected RX input, 2-stage OPA836 analog receive chain, envelope detector, ADC interface, TMP117 I2C temperature sensor, and status LEDs. Layout intent: piezo centered, RX chain within 10 mm of PIEZO_NODE, boost section remote from RX, digital and analog partitioning, and AGND/DGND star connection near RX front end.
