STM32F1 Firmware & PCB Co-Design

I have an STM32F103RB concept in mind and need an engineer who can sit virtually beside me while we bring it to life. We will be working in C inside STM32CubeIDE, focusing on three main software goals: processing data from sensors, exchanging information with connected peripherals, and guaranteeing reliable real-time control. For communications, everything will ride over UART, so efficient, interrupt-driven routines and solid error handling are essential. Once the firmware is stable, we will move straight into laying out the hardware. I’ll share the schematics I have so far; you will refine them, route the board, and prepare production-ready Gerbers. I prefer Altium or KiCad, but I’m open if you have a strong workflow in another tool that exports clean industry-standard files. Deliverables • Well-commented STM32F1 C source, CubeIDE project, and compiled binaries • Verified UART communication demos (loop-back and external device test) • PCB schematic and routed board with manufacturing files (Gerber, BOM, pick-and-place) • Brief build & bring-up guide so I can reproduce your results Acceptance criteria Firmware must run with cycle-accurate timing, pass basic sensor simulation tests, and log error-free UART traffic for 24 h. PCB must pass design-rule checks and be ready for a small-batch assembly run. If you enjoy collaborative, hands-on development and can jump on quick calls or screen-shares to hash out details, let’s start.
