Formal Power Budget for the module
| Component | Device Name | Operating Voltage | Peak Current | Notes |
|---|---|---|---|---|
| MCU | STM32F446RE/C | 3.3V | ~120mA | Assuming the following are active (Table 26 on Datasheet) STM at (f_hsi) 16MHz (up to 87mA)
|
| GPS Module | MAX-M8C | 3.3V | 67mA | Maximum-rated supply current. Typical operations typically run at <20mA |
| TX/RX Module | RFM95W | 3.3V | 120mA | Operating at full capacity. Will be used to ensure connection. |
| SPI to Ethernet | 3.3V | 128mA | 100M link | |
| NOR Flash | 3.3V | 25mA | R/W operations use between 20mA to 25mA. Standby power is 60uA. |
