STATUS: DONE DEPENDS: none

READ: docs/megaplans/INTEGRATION-MEGAPLAN.md, docs/JC4827W543_PIN_AUDIT_VERIFIED.md, components/board_jc4827w543/board.c, components/board_wroom/board.c

IN:

1. board_jc4827w543: add board_pin_motor_step() → 16, board_pin_motor_dir() → 15, board_pin_temp() → 17, board_pin_spk_bclk(), board_pin_spk_lrclk(), board_pin_spk_din() → 42, 2, 41; change board_pin_motor_en() → 7 (keep disable level 1 = active-LOW EN).
2. board_wroom: add matching board_pin_motor_step() → 12, board_pin_motor_dir() → 14, board_pin_temp() → 13 so HAL impls can be shared.
3. Update docs/CURRENT_STATE.md pin table note and JC4827W543_PIN_AUDIT_VERIFIED.md header section with the corrected labels if not already updated (P2: IO46/9/14/5, P3: IO6/7/15/16, P4: GND/3V3/17/18).

OUT: HAL implementations, business logic, NVS profiles. FORBIDDEN: GPIO46 for any output; stealing TF, QSPI, GT911, USB, or UART0 pins.

VERIFY: idf.py build succeeds for both esp32 and esp32s3 targets.

COMMITS:

1. Lock S3 header pins and introduce shared board pin accessors
2. Update pin audit documentation labels

DoD checkboxes:

• board_jc4827w543 pin accessors added.
• board_wroom pin accessors added.
• Build succeeds on both targets.
