K-Scale Motor Controller

This is the K-Scale Motor Controller design document.

Requirements

• Microcontroller
  • STM
  • Other:
    • Integrated motor control MCUs
      • Infineon XMC4800
      • Infineon XMC4500
      • NXP LPC1549
      • STM32F405RG
        • Used by ODrive
    • For high-precision and complex control tasks with an emphasis on real-time networking and performance, the Infineon XMC4800 is suitable.
    • If budget and simplicity are key considerations, and less intensive processing is required, the NXP LPC1549 offers a good balance.
    • For a balance between performance and ecosystem support, with flexibility in hardware and software, the STM32F405RG is an excellent choice.
    • MCUs (without integrated motor control)
      • RP2040

• Power supply
  • Assume we will have 48 volt power to the board

• Communication
  • CAN bus
    • Other
      • Texas Instruments ISO1050DUBR
  • 1 mbps

• Sensing
  • Temperature
    • Other
      • Maxim Integrated DS18B20
  • Absolute (single turn) position
    • Other
      • Infineon TLE5012B
      • AMS AS5047P
  • Current sensing
    • Other
      • Allegro ACS770

• Programming port
  • USB C
