Overview
Emmc adapter is an open-source printed circuit board by voltlog, from the voltlog/emmc-wfbga153-microsd repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 20 × 33.5 mm with 8 parts on 14 nets, routed with 827 tracks and 27 vias.
It is built around the THGBMNG5D1LBAIL. Its parts include 2 capacitors, 1 IC and 1 connector. It belongs with the interfaces and adapters boards of this library.
Main components
1README
README.mdeMMC WFBGA153 to microSD card adapter PCB
This adapter can be used for data recovery purposes by soldering a WFBGA eMMC chip and connecting to a standard microSD card reader for read/write operations or if you would like to build an inexpensive storage device using cheap memory chips obtained from Ebay/Aliexpress or salvaged from other devices. Image below shows the adapter assembled with a Toshiba 4GB eMMC chip.
What else do you need?
Besides this custom designed PCB you will need a couple of bypass capacitors (0.1-1uF 10V or above in 0603 package) and the eMMC memory chip. eMMC chips in WFBGA153 package are available from every big distributor but if you would like to try your luck with some inexpensive options, check out this link.
Alternatively you can order this PCB adapter from my Tindie store.
More info about this project in Voltlog #351.

Questions
How big is the Emmc adapter PCB?
It measures 20 × 33.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Emmc adapter use?
8 parts, built around the THGBMNG5D1LBAIL. 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 Emmc adapter KiCad files?
From the voltlog/emmc-wfbga153-microsd repository on GitHub, at the commit this page was made from: the board is emmc-adapter.kicad_pcb and its schematic emmc-adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Emmc adapter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
