Attendance Device PCB and HMI Design

PCB Designer Needed – Attendance Device Need an experienced PCB designer for an attendance device. Main Components - STM32 Blue Pill (STM32F103) - 7" DWIN HMI - Fingerprint sensor - Ethernet (LAN) port - RTC - Micro SD card reader - DC barrel jack power input - Power regulation circuitry - Voltage divider circuits - GPIO expansion headers Detailed BOM and component list will be provided. Scope - Schematic design - PCB layout and routing - Manufacturing-ready Gerber files - Design review and prototype support - DWIN screen UI/page design and configuration - Work with us during firmware development and testing to resolve hardware/software integration issues - Support board bring-up until major functions are operational Responsibilities - You will be responsible for PCB design and DWIN HMI development/configuration. - We will handle the STM32 firmware implementation. - Coordination will be required to define communication protocols and ensure smooth integration between the STM32 firmware and DWIN interface. Deliverables - Schematic files - PCB design files - Gerbers - Pick & Place files - Assembly drawings - DWIN project/source files - Final BOM documentation When Applying Please share: - Similar STM32-based projects - Experience with DWIN HMI design - PCB software used (Altium, KiCad, EasyEDA, etc.) - Cost and timeline - Availability for post-design support This is not a design-and-forget project. We need someone willing to collaborate through prototype testing and firmware integration.
