schemdraw

Schemdraw is a python package for producing high-quality electrical circuit schematic diagrams. Typical usage:

import schemdraw
import schemdraw.elements as elm
with schemdraw.Drawing(file='schematic.svg') as d:
    elm.Resistor().label('100KΩ')
    elm.Capacitor().down().label('0.1μF', loc='bottom')
    elm.Line().left()
    elm.Ground()
    elm.SourceV().up().label('10V')

Included are symbols for basic electrical components (resistors, capacitors, diodes, transistors, etc.), opamps and signal processing elements. Additionally, Schemdraw can produce digital timing diagrams, state machine diagrams, and flowcharts.
