Determine your power source – Determine what you will use to supply power to the Pico (battery, wall adapter, etc). Connect the positive and ground wires – If your Pico has male headers soldered into place, you will need to connect the positive and negative ground wires to the Pico. Pin 39 is the VSYS pin capable of accepting power.
ICs using bipolar transistors have VCC (positive) and VEE (negative) power supply pins. In single supply systems (e.g., most modern digital and analog circuits) the negative power supply pin is also commonly referred to as GND. In "split rail" supply systems (e.g., older analog circuits) positive, negative and ground power supply pins are used.
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons that will flow through an external electric circuit to the ...
