We are a B2B company building AI-powered cameras for the retail market, and we're looking for an experienced hardware engineer to design a custom, battery-powered AI camera mainboard. The board is built around the STM32N657 (Cortex-M55 + Neural-ART NPU) and integrates a MIPI CSI-2 day/night camera, Wi-Fi 6 / BLE, a 1S2P 9600 mAh Li-ion power subsystem (switching charger + fuel gauge), IR + white illumination drivers, audio, microSD and USB-C. This engagement is hardware only: schematic capture, multilayer PCB layout (likely 6–8 layers, Altium), full manufacturing files with native sources, and 3–5 assembled, tested samples. Firmware is handled in-house. Two skills are non-negotiable: STM32N6/H7 designs with external boot flash, and routing MIPI CSI-2 camera interfaces with controlled impedance. We have a validated reference design on the same SoC to share as a functional reference. We plan a phased approach (a relaxed dev board first, then the final compact board) and target a market launch in 4–6 months. In your proposal, please include an anonymized example of a past external-boot STM32 and/or MIPI CSI-2 board, your recommended stackup, and an itemized quote. Proposals that skip these won't be considered.

Hello, My name is Sardar Hasnain Ali, Electronics Engineer and CEO of MHTechFusion. We are a Germany-based, husband-wife led IoT and embedded hardware startup with a core technical team and lab setup for PCB design, prototyping, bring-up, and testing. Your custom battery-powered AI camera mainboard is well aligned with our experience in multilayer embedded hardware, STM32-based designs, external boot flash, wireless IoT, power subsystems, camera/vision boards, and manufacturing-ready prototypes. For this project, we can support schematic capture, 6–8 layer PCB layout in Altium, controlled-impedance routing for MIPI CSI-2, power tree design, charger/fuel gauge integration, illumination/audio/microSD/USB-C sections, BOM, Gerbers, assembly files, native Altium sources, and 3–5 assembled tested samples. Recommended stackup: 8-layer for final compact board, with solid GND reference layers for MIPI/USB/Wi-Fi, separated power planes, and short controlled-impedance camera routing. A 6-layer relaxed dev board can be used first for faster validation. We can share anonymized examples of previous STM32 external-flash and camera/vision-related boards during discussion. Quote can be itemized by dev board design, prototype assembly/testing, final compact board design, and final sample production. Let’s connect and set up a meeting to discuss potential collaboration. Best, sardar (ceo MHTechFusion)

DearSir, With over a decade's experience in electrical and hardware engineering, I am thrilled about the prospect of working on your AI camera mainboard project. My proficiency in designing innovative embed set-ups will enable a synergy with the STM32N657 and Neural-ART NPU, as well as the MIPI CSI-2 interfaces you prioritize. To that end, I can provide an erroneous example board design that employs external boot flash and routing for MIPI CSI-2 interfaces with controlled impedance. My familiarity with tools like Altium, OrCAD and Easyeda is also essential for this job. It has played a crucial role in my previous works, ensuring system efficiency while meeting specific power and noise requirements, giving you multiple valid stackup. Moreover, my expertise in digital motor control and power electronics is quite applicable to your project as it showcases my capability to work with 1S2P 9600 mAh Li-ion power subsystems. I possess hands-on experience with baud batt+fuel gauge technology integration. I've even built renewable energy systems resembling your project's use of sophisticated power sub-systems. Hence, my skills are tailor-made for this job. In closing, I am confident that combining my knowledge in electrical design with your specifications will result in a groundbreaking product launch within the agreed-upon timeline. Let's bring your B2B AI-powered cameras to life!

Hello, Your phased development approach is well suited for a complex AI camera platform, and I can support the complete hardware design from schematic capture through production-ready PCB layout. My experience includes STM32-based embedded systems, high-speed multilayer PCB design, external QSPI/OSPI boot flash, battery-powered products, power management, USB-C, imaging peripherals, and RF-aware layouts. For this design, I would recommend a 6-layer stack-up for the development board and evaluate an 8-layer stack-up for the compact production version if signal integrity, MIPI CSI-2 routing density, and EMI require additional reference planes. Particular attention will be given to controlled-impedance MIPI routing, DDR-length matching where applicable, RF isolation, power sequencing, thermal management, and DFM/DFT to ensure a smooth transition to manufacturing. I can deliver complete Altium source files, manufacturing outputs, BOM, assembly documentation, and support prototype bring-up. I can also share relevant embedded hardware examples privately and provide an itemized milestone-based quotation after reviewing your reference design and component selection.
