Formal Power Budget for the module

ComponentDevice NameOperating VoltagePeak CurrentNotes
MCUSTM32F446RE/C3.3V~120mAAssuming the following are active (Table 26 on Datasheet)
STM at (f_hsi) 16MHz (up to 87mA)
  • SPI_1 (WIZNET)
  • I2C (GPS)
  • SPI_2 (TX/RX Module)
  • SPI_3 (NOR Flash)
  • 4x 2mA pins (for status LEDs)
GPS ModuleMAX-M8C3.3V67mAMaximum-rated supply current. Typical operations typically run at <20mA
TX/RX ModuleRFM95W3.3V120mAOperating at full capacity. Will be used to ensure connection.
