Eagle 2: Libraries

by gaussmarkov

Finding the appropriate components can be frustrating in the default Eagle setup. Component libraries for CadSoft’s Eagle Layout Editor and diy pedals are available in the zip file linked here: gm-lbr.zip. These libraries gather many of the common components used by diy pedal builders, grouping components by type and indicating values associated with each package size.

Installation of these libraries is described in the post Eagle 3: Setup.

Below is a descriptive list of the component libraries, showing their organization. Additional detail appears on the page eagle: components, which also explains how to add components to a schematic in Eagle’s schematic layout editor.

Library Description
capacitors, ceramic
  • very small capacitances: 1 – 1000pF
capacitors, electrolytic, polarized
  • large value capacitors: .22 – 470uF (uF = μF = mF)
  • often used in power supply filters
capacitors, film, box
  • 1000pF – 2.2uF (uF = μF = mF)
  • popular nonpolarized capacitors because they are small
  • these have short leads so that pad spacing equals lead spacing
  • e.g., WIMA capacitors
capacitors, film, chicklet
  • 100pF – 0.1uF (uF = μF = mF)
  • popular nonpolarized capacitors
  • available from smallbearelec.com as Panasonic ECQ-B capacitors
  • these become quite large for values near 1uF
capacitors, silver mica
  • very small capacitances: 1 – 1000pF
capacitors, tantalum
  • used in the signal path for special character
  • found in the tone stack of a ts808 clone
  • Zener 1N47xx (as in protection for the MOSFET in the AMZ MOSFET Booster)
  • rectifier 1N4001-1N4008 (for polarity reversal protection in power supply sections)
  • clipping 1N914 (as in a TS808)
  • LED (light emitting diode, 3mm and 5mm)
  • mostly gathered from Eagle libraries
  • a wah inductor
integrated circuits
  • mostly op amps (e.g., 4558, TL072)
  • also CD4049 (for Anderton’s Tube Sound Fuzz, the Red Llama, …)
  • generally gathered from Eagle libraries
  • audio and power jacks
  • off-board versions and just pads for the circuit board
  • chassis-mount (e.g., Alpha 16mm) pots
  • board-mount trim pots (1/4″ and 3/8″)
  • all pot values have the same size package; you choose the value of resistance
  • 78* voltage regulators like the 7805 or 78L05 for producing 5V
  • 3mm long — the size of 1/8 watt resistors
  • 6mm long — the size of 1/4 watt resistors
  • all resistor values have the same size package; you choose the value of resistance
  • input, output, ground, and power supply.
  • these are used on a schematic for placeholders and on a board for pads for off-board components like jacks.
  • small signal amps (e.g., 2N508x)
  • switching transistors (e.g., 2N2222, 2N390x)
  • JFETs (e.g., J201, 2N3819, 2N5457)
  • MOSFETs (e.g., BS170, BS250)
  • mostly copied from Eagle libraries
  • Xicon 42T* transformers available at mouser.com (from Eagle libraries)
  • Edcor 10K/10K transformer
  • ideal voltage and current supply symbols for electronic theory schematics

    Thank you SOOOOO much for making your libraries available! I’d tried making some of my own, but things weren’t working out so well as I’m still quite new to Eagle. Yours provided me with almost everything I need. The only thing left that I’m looking for is some THAT Corp. ICs.
    Once again, thanks for your generosity!
    Kind regards,

    Great lbr!

    Although I still seem to be missing the lm386…

    Any word or solution on this?

    You are all most welcome and your comments are much appreciated. I’m sorry that I haven’t had time to get back to this project in years. It’s great that it is still paying dividends. All the best, gm

    Dear gaussmarkov why not add your libraries to github???? so people can post you their parts and see changes and so on… see for example https://github.com/sparkfun/SparkFun-Eagle-Libraries if you give me permission I can post it on github
