What voltage does the Raspberry Pi Pico require?

The Pico accepts a wide input voltage range from 1.8V to 5.5V on its VSYS pin. This flexibility allows powering it from a single-cell LiPo battery (~3.7V), USB 5V, or regulated power supplies. The onboard switching regulator converts VSYS to a stable 3.3V for the RP2040 chip and peripherals.

How much current does the Raspberry Pi Pico consume?

Current consumption varies by mode and usage:

  • Idle mode: ~38 mA
  • Active mode (with code running): ~43 mA
  • Deep sleep mode: ~16 mA
  • Pico W with WiFi active: Peaks can reach 100-150 mA during startup, with steady state around 40-70 mA depending on WiFi activity.

These figures depend on peripherals, CPU frequency, and software optimization.

Can the Raspberry Pi Pico be powered via USB?

✅ Yes! The Pico is commonly powered via its micro USB port, which supplies 5V. This is the easiest and most reliable method for development and prototyping. However, ensure your USB cable and power source can deliver stable current, especially when using power-hungry peripherals or WiFi on the Pico W.

A regulated 5V USB power supply with at least 500 mA current capability is recommended for most use cases. For battery-powered projects, LiPo batteries with appropriate voltage regulators or buck converters are preferred to maintain efficiency and prevent brownouts.

Remember to include a battery management system (BMS) or charging circuit if using rechargeable batteries.

How to measure power consumption on a Raspberry Pi Pico?

To measure current draw:

  1. Use a digital multimeter (DMM) capable of measuring milliamps.
  2. Connect the multimeter in series with the power supply line (e.g., between USB 5V and Pico VSYS).
  3. Use the DMM’s mA or μA range depending on expected current.
  4. Avoid powering the Pico from USB and battery simultaneously unless proper protection diodes are used.

This method helps profile power consumption during different modes and activities.

Always ensure your power source meets the Pico’s voltage and current requirements, especially during startup surges.

How can I reduce power consumption on the Raspberry Pi Pico?

  • Use deep sleep modes (machine.deepsleep()) to drop current to ~16 mA.
  • Reduce CPU frequency from 125 MHz to 20 MHz or lower if possible.
  • Disable unused peripherals and LEDs.
  • Optimize code to avoid busy loops.
  • Use efficient power regulators (buck converters) instead of linear regulators.
