Smart iPhone Selfie Display with BLE

to make selfie photos from the back camera of the iPhone

Droid Technologies designed and developed a smart selfie accessory for iPhone, enabling users to take high-quality selfies with the phone’s rear camera while viewing themselves on an external display.

The system uses an STM32H7 as the main controller and an STM32WB for Bluetooth Low Energy (BLE) communication with the iPhone. BLE allows the device to remotely trigger the iPhone camera shutter, while the integrated display and auxiliary camera help users frame and position shots accurately.

The device also integrates wireless charging, allowing the iPhone to remain powered during use.

Key features and engineering scope:

• STM32H7 main controller
• STM32WB BLE controller
• Bluetooth Low Energy communication
• Remote iPhone camera shutter control
• Integrated display and auxiliary camera
• Real-time selfie framing
• Wireless charging integration
• Custom PCB and hardware design
• Embedded firmware development
• Display and camera integration
• Hardware and firmware testing

This project demonstrates Droid Technologies’ expertise in consumer electronics development, STM32 firmware development, BLE accessories, camera integration, display systems, wireless charging, and custom embedded devices.
