STM32 BLE Module Migration

changed my mind. instead do stm32 mcu + external bt module. for now use
Design the BLE section specifically for future migration to ANNA-B565. Use only the common ANNA-family power, UART, reset and control functionality required for u-connectXpress. Avoid routing unused B112-specific GPIOs. Reserve the complete 6.5 × 6.5 mm module region and antenna keepout so the land pattern can be modified for ANNA-B565 without moving surrounding circuitry. or ANNA-B412 maybe intermediate change. And architect it:
STM32U575 │ │ UART TX/RX │ RTS/CTS │ RESET │ optional GPIO WAKE ▼ ┌────────────────┐ │ ANNA-B112-02B │ prototype │ 6.5 × 6.5 mm │ └────────────────┘
      ↓ future PCB revision
┌────────────────┐ │ ANNA-B565 │ │ 6.5 × 6.5 mm │ │ nRF54L15 │ └────────────────┘

No design changes were made; the project remains empty. I couldn’t inspect the attachment or build the STM32U575 + ANNA-B112/B412 migration-ready BLE section because AI execution features are unavailable without ACUs.
Remaining work:
  • Verify ANNA-B112, ANNA-B412, and ANNA-B565 common power/UART/RTS/CTS/reset/wake pins and antenna constraints.
  • Add the STM32U575 and prototype ANNA module circuitry.
  • Reserve the full 6.5 × 6.5 mm module area and antenna keepout.
  • Route only the shared u-connectXpress interface, avoiding B112-specific GPIO dependencies.
  • Document the future B565 land-pattern migration and verify schematic/ERC/layout constraints.
