# `lukeshu-74xx-74CBTLV3257.kicad_sym`

I have modified https://gitlab.com/kicad/libraries/kicad-symbols :
`74xx.kicad_sym` : `74CBTLV3257` to be a single unit, instead of being
split across 5 units.

# `lukeshu-Connector-Micro_SD_Card.kicad_sym`

I have modified https://gitlab.com/kicad/libraries/kicad-symbols :
`Connector.kicad_sym` : `Micro_SD_Card` to be an actual microSD Card,
instead of a socket for a microSD card.

# `lukeshu-Connector-Micro_SD_Socket.kicad_sym`

Given the above `Micro_SD_Card`, I made another copy of
https://gitlab.com/kicad/libraries/kicad-symbols :
`Connector.kicad_sym` : `Micro_SD_Card` and just renamed it
`Micro_SD_Socket`, for clarity.

# `lukeshu-Connector-RJ45_Cetus_J1B1211CCD.kicad_sym`

I have modified https://gitlab.com/kicad/libraries/kicad-symbols :
`Connector.kicad_sym` : `8P8C_LED_Shielded` to create a symbol
sepecific to the Cetus J1B1211CCD (an RJ45 jack with built-in
magnetics):

 - I added pin names (and widened the main rectangle to make room for
   the pin names)
 - I added specific footprint information.

# `lukeshu-Interface_Ethernet-W5500.kicad_sym`

I have modified https://gitlab.com/kicad/libraries/kicad-symbols :
`Interface_Ethernet.kicad_sym` : `W5500`:

 - I un-stacked the power pins.  I like to see them, especially if
   they each need a decoupling capacitor.
 - I removed the reserved-NC / NC / DNC pins, to make the size more
   reasonable.

# `lukeshu-MCU_RaspberryPi-RP2040.kicad_sym`

This is a fusion of
https://datasheets.raspberrypi.com/rp2040/Minimal-KiCAD.zip :
`RP2040_minimal_r2/MCU_RaspberryPi_RP2040.lib` and
https://gitlab.com/kicad/libraries/kicad-symbols :
`MCU_RaspberryPi.kicad_sym` (which appears to be descended from, or at
least share a common ancestor with the aforementioned
`MCU_RaspberryPi_RP2040.lib`).  This was done with `kicad-cli sym
upgrade`, and good ol' Emacs and `diff`.

Compared to Raspberry Pi's version:
 - Has improved footprint/datasheeet/description/keywords metadata
   taken from the kicad-symbols version.
 - The pin types of SWCLK and TESTEN have been fixed.
 - The stroke-type for the main rectangle has been changed from
   `solid` to `default` (to match the kicad-symbols version).
 - The QSPI pins have been re-ordered.
 - Some positions positions have been nudged by <50mil to conform to
   the [KiCad Library Conventions][KLC].

Compared to the kicad-symbols version:
 - The size, pin-layout, and text-layout are different.
 - The power-in pins are not "stacked" (all matching pins have the
   same location, and all but one of them are given `hide=yes`,
   `type=passive`).  The [KiCad Library Conventions][KLC] say "Power
   supply pins must be stacked unless the datasheet specifies the need
   for decoupling capacitors on every pin."  The [Hardware design with
   the
   RP2040](https://datasheets.raspberrypi.com/rp2040/hardware-design-with-rp2040.pdf)
   document states that each pin should get its own decoupling
   capacitor, but that this is negotiable; so I have un-stacked them
   to encourage separate decoupling capacitors.

Compared to both Raspberry Pi's version and the kicad-symbols version:
 - The pin type of XOUT has been fixed.
