Overview
LCSP072rev2 is an open-source printed circuit board by cue-bus, from the cue-bus/Sharp-MCP-72BGA repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board of 18.4 × 61.5 mm with 5 parts on 53 nets, routed with 245 tracks and 30 vias.
It is built around the TSOP4838. Its parts include 3 connectors, 1 capacitor and 1 IC. It belongs with the interfaces and adapters boards of this library.

Breakout adapter for Sharp MCP chips in BGA72 package
Most Sharp MCP flash chips use the same main pinout for the the flash interface, but provisions have been made on the adapter board to allow for changes if necessary.
- Pin 47 can either be NC, CE2, or VCCQ depending on the chip. It is prewired to ball H3, but if necessary, cut the trace where indicated and wire a jumper wire from Pin 47 to wherever it's needed.
- A10 and H10 have functions on some chips, so they are broken out to allow for easy access if necessary. Otherwise, these can be left as NC. Ball H10 is CE2 on a few single-die Sharp chips, but so far every MCP has featured CE2 on ball H3.
- Chips under 32mbits use a slightly different DIP pinout that this adapter maps to the BGAs. For chips of this size, either swap pins 9 and 15, or simply read the chip as 64mbit and truncate the file to the necessary size.

Questions
How big is the LCSP072rev2 PCB?
It measures 18.4 × 61.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LCSP072rev2 use?
5 parts, built around the TSOP4838. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LCSP072rev2 KiCad files?
From the cue-bus/Sharp-MCP-72BGA repository on GitHub, at the commit this page was made from: the board is kicad/LCSP072rev2.kicad_pcb and its schematic kicad/LCSP072rev2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LCSP072rev2 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
