Video-Streaming Smart Glasses PCB Design

About the project

# Custom PCB Design for Camera Smart Glasses I am looking for an experienced **embedded hardware/PCB designer or engineering firm** to design a complete PCB for camera-equipped smart glasses capable of **still photo capture and live video streaming**. ## SoC The designer can select the most suitable SoC from: * **Allwinner V821** * **Rockchip RV1103** * **Rockchip RV1106** Please recommend the best option based on **camera/MIPI support, power consumption, thermals, USB capabilities, software/SDK support, availability, and PCB complexity**. Reference designs that may be used include **LicheeRV Nano, Luckfox Pico Mini, and Avaota F2**. ## Core Requirements * Single onboard **Sony IMX or equivalent camera**, minimum 1080p * MIPI CSI-2 camera interface * Still photo capture + live video streaming * USB connection to an **Android/iPhone host application** * USB must be implemented appropriately for reliable video/data transfer * UART debug interface * SPI, I²C and GPIO expansion/test pads * Boot storage: SPI Flash/eMMC/microSD as appropriate * Status LED, user button, reset and programming/debug interfaces * Optional Wi-Fi/Bluetooth expansion pads if space/power permits * Low-power and thermally suitable for a wearable device ## PCB Design Design a **4-layer or higher multilayer PCB**, with proper: * MIPI CSI-2 and USB differential routing * Controlled impedance * Differential-pair length/skew matching * Continuous reference/return paths * High-speed via optimization * Power/ground plane design * Decoupling and power integrity * EMI/EMC-conscious layout The PCB should be designed for manufacturing and follow the selected manufacturer's impedance/stack-up requirements. ## Scope of Work 1. Evaluate the three SoCs and recommend one. 2. Analyze the relevant reference design. 3. Create the system block diagram. 4. Design the complete schematic. 5. Create/verify symbols and footprints. 6. Design the multilayer PCB. 7. Route and verify MIPI CSI-2, USB and other interfaces. 8. Perform ERC/DRC and design review. 9. Generate manufacturing files. 10. Support prototype bring-up/debugging if required. ## Deliverables * Complete **KiCad/Altium/EasyEDA source files** * Schematic * PCB layout * Gerbers + drill files * BOM with manufacturer part numbers and alternates * Pick-and-place/assembly files * PCB stack-up and impedance requirements * 3D STEP model * ERC/DRC reports * Basic design documentation * Online design-review session ## Acceptance Criteria The prototype should: * Boot reliably * Initialize the camera * Enumerate/connect over USB * Support communication with an Android/iPhone host * Stream **at least 720p30** * Support still-image capture * Operate without significant thermal issues * Have no obvious EMI/EMC or signal-integrity issues in a basic pre-scan ## Please Include in Your Proposal * Relevant PCB/high-speed design experience * Previous **MIPI CSI-2 / camera** projects * Experience with **Allwinner/Rockchip SoCs** * Examples of similar work * Preferred design software * Estimated **cost and timeline** * Whether you can support **prototype bring-up and debugging** * Whether complete source files will be provided at project completion
