ERC Violations After REV-FINAL Capture
Reviewed at: 2026-05-30T15:43:58Z
Scope: Electrical Rule Checks after applying REV-FINAL active schematic wiring and preserving U3/LM66100 battery-backup ideal-OR topology as an OPEN EE REVIEW ITEM. DNP blocks remain placed and electrically inactive.
Summary:
  • Total unresolved ERC checks: 115
  • Errors: 8 Missing Power
  • Warnings: 107 Floating Pin
Missing Power errors (8)
  1. Power input not connected: UCMP1:VCC (net: —) — DNP TLV7011 comparator footprint.
  2. Power input not driven: J1:VBUS (net: +5V_USB) — USB-C VBUS is an external input/source flag issue.
  3. Power input not driven: J1:VBUS__1 (net: +5V_USB) — USB-C VBUS duplicate pin, external input/source flag issue.
  4. Power input not connected: U_CANFD:VDD (net: —) — DNP MCP2518FD CAN-FD controller footprint.
  5. Power input not connected: UINA2:VS (net: —) — DNP INA181 current-sense footprint.
  6. Power input not connected: UINA1:VS (net: —) — DNP INA181 current-sense footprint.
  7. Power input not connected: ADS1115:VDD (net: —) — DNP ADS1115 footprint.
  8. Power input not connected: UCMP2:VCC (net: —) — DNP TLV7011 comparator footprint.

Notes
  • U3A/U3B LM66100 were not deleted and remain populated. The SYS_BACKUP_OR_OPEN_EE and AXP_SYS_SRC_OPEN_EE nets are flagged with an EE Review property for the open ideal-OR/battery-backup topology item.
  • The active required interfaces are present in the schematic: I2C on IO7/IO8, thermocouple SPI on IO17/18/21 with CS IO38/39/40/41 and FAULT IO42, CAN via SN65HVD230 using ESP32-S3 TXD0/RXD0 module pins representing IO43/IO44, C6 esp-hosted SPI on IO9/10/11/13 plus IO14 handshake and IO15 reset, beeper PWM on IO16, display QSPI on IO1-6/12, and USB D-/D+ on IO19/IO20.
  • Remaining violations are intentionally not auto-resolved where they touch DNP footprints, open connector pins, or the EE-review power topology.

  • Missing Power errors (8)

  • Floating Pin warnings (107)
