Power for the Raspberry Pi Pico - Guide to using VBUS, VSYS and 3V3 for external power circuits

This video covers all you need to know about powering the Raspberry Pi Pico, or using the Raspberry Pi Pico to power external circuits. It will help you to understand VBUS vs VSYS and how to safely connect to external power and USB power at the same time. It also includes circuits for powering the Pico or using the Pico to power other circuits using the 3V3 pin. The following circuits are included in the video: * Raspberry Pi Pico Schematic (power section) * Powering the Raspberry Pi Pico through VBUS * Powering the Raspberry Pi Pico through VSYS This mostly apply the same for the Raspberry Pi PicoW except that there is a different model of buck-boost convertor used in the Pico W. For more details, including the circuit diagrams and a schematic of the Raspberry Pi Pico power section see my guide to powering the Raspberry Pi Pico at: http://www.penguintutor.com/electronics/pico-power Understanding AC to DC power conversion (video): https://youtu.be/chEVmKcakaU Controlling NeoPixels on a Raspberry Pi Pico using CircuitPython: http://www.penguintutor.com/programming/circuitpython Guide to MOSFET level-shifters for controlling RGB LED NeoPixels: http://www.penguintutor.com/electronics/mosfet-levelshift Chapters: 00:00 Power to the Pico 00:35 Powering a Pico 01:18 Pico power specifications 05:36 Pico Power Pins 12:42 Power circuit diagrams 18:32 Special Situations
