Advanced STM32 Motor & Heater Control Production
Budget: ₹1,500 – ₹12,500 INR
STM32 BLDC Motor + Heater Controller — KiCad Schematic, PCB, Gerbers & BOM (Production)
Project Description (paste this)
I need an experienced hardware/PCB engineer to redesign an existing Arduino/IR2104-based motor controller into a production-grade STM32-based controller board using KiCad.
Scope:
• Full KiCad schematic (multi-sheet) and 4-layer PCB layout
• 24V 3-phase BLDC motor control with hall-sensor feedback
• Integrated 3-phase gate driver + MOSFET bridge (modern driver preferred)
• 24V heater control with temperature feedback and hardware fail-safe
• I2C ToF/distance sensor connector (VL53L0X-class)
• UART interface to a main controller, incl. UART-bootloader OTA path (BOOT0/NRST control)
• SWD debug/recovery header
• Power tree: 24V + 16V inputs, buck-based regulation, reverse-polarity/TVS/fuse protection
• Future load-sensor connector (DNP/unpopulated, routed only)
• Full test points and production diagnostics
Deliverables:
• KiCad project (schematic + PCB source files)
• Passing ERC and DRC
• Gerbers, drill files, BOM, and pick-and-place (CPL) files
• Manufacturing-ready output package
I will provide a complete engineering handoff pack: pin map, connector pinouts, net table, recommended BOM, footprint table, layout constraints, and a detailed implementation spec. This is a “build to spec” job, not a blank-sheet design — so I need someone who can execute precisely and flag issues.
Required skills: KiCad (v7/v8), STM32, BLDC motor drivers, power electronics, DFM, 4-layer layout.
To bid, please include:
1. Links/images of past STM32 or motor-driver boards you’ve done
2. Your KiCad version
3. Rough timeline
4. One thing you’d want clarified before starting
