This is the K-Scale Motor Controller design document.

Microcontroller
- STM
- Other:
  - Integrated motor control MCUs
    - Infineon XMC4800^[1]
    - NXP LPC1549^[2]
    - 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

Communication
- CAN bus
  - Other
    - Texas Instruments ISO1050DUBR ^[3]
- 1 mbps

Sensing
- Temperature
  - Other
    - Maxim Integrated DS18B20 ^[4]
- Absolute (single turn) position
  - Other
    - Infineon TLE5012B ^[5]
    - AMS AS5047P ^[6]
- Current sensing
  - Other
    - Allegro ACS770 ^[7]
