Reference Component List
| Component | Purpose | Sourcing notes |
|---|---|---|
| Two-axis servo pan/tilt bracket | Mechanical structure for horizontal and vertical motion. | Generic 2-axis pan/tilt kits are widely available from electronics hobby suppliers. |
| Two standard PWM hobby servos | Drive horizontal and vertical axes. | Common SG90/MG90S-style servos or equivalent can be used depending on payload. |
| BLE UART module or BLE-enabled microcontroller | Receives Bluetooth control commands from the iOS app. | Any compatible BLE UART controller can be used if it implements the expected command interface. |
| Servo controller / microcontroller | Converts received control commands into servo PWM signals. | Can be an Arduino-compatible controller, ESP32-class BLE controller, or a custom microcontroller board. |
| External 5V power supply | Powers the servos safely. | Servo power should be sized for the selected motors and should not be drawn directly from the iOS device. |

App Compatibility Notes
HandPoseTracker can run without the external hardware to show the camera preview, hand detection overlay, and tuning interface. The physical gimbal motion requires compatible DIY BLE hardware.
The app also contains a hardware control workflow for compatible accessories through public iOS frameworks where available. No third-party product name, logo, or proprietary hardware branding is used in the App Store metadata.
