  • Supports 18V~28V for 6S battery (rough calcs, 3V-4.6V max per cell)

  • 3x4 header inputs (question) & outputs

    • Input:

      • CAN, GND from PIxhawk (creating own 5V PWR)

    • Ouput:

      • PWM, PWR, GND

  • 30.5mmx30.5mm board to comply with Mounting Hole Specifications

Components

notes:

  • input cmc (question) ← perhaps not needed, check 12s doc to read why they implemented

  • current sense

    • use INA180 unless determined otherwise

    • shunt resistor: calculate for it? to be looked up

  • buck converter

    • check if existing solves, check for board space

    • if not, make buck with lower input voltage & smaller inductor to maximize board space

  • LDO

    • does current one from can circuit solve? if not look for other one

    • purpose is to reduce noise from buck.. consult esc can doc for details (question)

  • diode

    • what kind of diode… to be looked up (question)

  • current limiting eFuse

    • current ones probably solve, however finding a singular IC with 4 channels instead could be better → maximizes board space

    • try and do some component selection here; will probably ask more questions

    • determine whether 4channel efuse vs 4 individuals will be better

      • things to consider:

        • cost

        • board space

        • power dissipation (question) probs not super critical

        • if 4 channels exist for this purpose

  • thermistor

    • not sure how to select one, will see later, not super high priority
