Connected Wearable Reference-Design Journey¶

This reference journey provides a repeatable path for a compact connected product with a display, BLE, a sensor input, and battery power. It is not a released schematic; use it to organize validation before designing custom hardware.

1. Select and baseline. Use SF32 Family and Choose Hardware, then run SiFli-SDK hello_world on an SF32LB52-DevKit-LCD or the closest available board.
2. Prove product functions. Follow Tutorials to validate input/sensor handling, BLE, a simple UI, storage if needed, and the serial recovery path.
3. Validate system interactions. Use Graphics, Bluetooth, and Low Power to test display refresh, wireless activity, and sleep/wake together.
4. Prepare custom hardware. Use the selected chip's design guide and checklist through Design for Production; confirm display, storage, battery, antenna/RF, and programming/test assumptions.
5. Release with evidence. Preserve the board name, SDK version, known-good image, logs, power scenes, recovery/OTA behavior, BOM choices, and checklist decisions.

The exit criterion is not a successful demo. It is a repeatable build/flash/recovery path plus measured evidence that the product's defining subsystems coexist on representative hardware.
