• Total Power Consumption: Approximately 427.38 mW

• RP2040: 28.1%
• LoRa-E5: 26.0%
• SD Card: 14.0%
• MEMS Microphone (SPH0645LM4H-B): 0.3%
• RT8059: 0.1%
• LEDs: 28.1%
• Other ICs: 2.3%
• Resistors and Passives: 1.2%

• RP2040: 120 mW (Assumed 40 MHz operation)
• LoRa-E5: 111 mW (Operation current at 868MHz transmitter mode)
• SD Card: 60 mW
• MEMS Microphone: 1.08 mW
• RT8059: 0.3 mW
• LEDs: 120 mW (Assuming 6 LEDs, each consuming 20mA at 2V)
• Other ICs: 10 mW (Estimated consumption for other small ICs)
• Resistors and Passives: 5 mW (Estimated consumption for passive components)

• This estimation involves several assumptions, such as standard operating currents and typical usage scenarios.
• Precise current consumption from components like the SPH0645LM4H-B and W25Q128JVSIQ were not included as their datasheets were not available at this moment.
• You might need to adjust these values based on your specific use case and component operating conditions.
