This is a repository of KiCad schematic symbol libraries:
Cypress_PSoC.libcontains a few Cypress PSoC 5LP chips.Cypress_cy8c5xlp.libcontains all the Cypress PSoC5LP chips.gowin_fpga.libcontains all the GOWIN FPGAs.Lattice_ECP5_FPGA.libcontains the Lattice ECP5 & ECP5-5G FPGAs.Lattice_iCE_FPGA.libcontains the Lattice iCE40 HX, LM, LP & Ultralight FPGAs.pic32.libcontains the PIC32 MX 1XX/2XX 28/36/44-pin microcontrollers.wch.libcontains the WCH CH54* and CH55* 8051 microcontrollers.xess.libcontains a grab-bag of parts, many auto-converted from Eagle.xilinx6s.libcontains all the Xilinx Spartan-6 FPGAs.xilinx6v.libcontains all the Xilinx Virtex-6 FPGAs.xilinx7.libcontains all the Xilinx 7-Series FPGAs (Zynq, Artix, Kintex, Spartan and Virtex).xilinxultra.libcontains all the Xilinx Ulatrascale FPGAs (Zynq, Kintex and Virtex).
OK, people are picky. Maybe even more picky when they're getting something for free. (There's probably a psychology paper in there, somewhere.)
The good thing is: you can change these schematic symbols!
Obviously you can modify any individual symbol using the KiCad schematic symbol editor.
But you can also make library-wide changes using the kipart utility as follows:
- Use the
kilib2csvutility to convert one or more of the libraries into a CSV file. - Open the CSV file as a spreadsheet and reorder the pins, change pin types, assign pins to different units, etc.
- Finally, run
kiparton the modified CSV file to create your own custom library. - Bask in the glory of your own originality.
Some of the schematic symbols in these libraries have changed! If you previously downloaded and used a library, you may find a newer version has differences like rearranged pins. Including a changed library in an existing schematic could cause errors! Either checkout the library that corresponds to the one you've already been using (look at the check-in dates), or verify that the symbols from the new library attach to the correct nets in your schematic.
