What can you do with this adapter?

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 to build a working adapter?

Besides getting 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.

Design features

The PCB was designed as a double sided board with the correct thickness of 0.8mm to match a standard microSD card. Some of the inner signals on the WFBGA153 footprint were escaped by routing through NC pins out to the edge. The boards were manufactured with ENIG gold plating finish to ensure the highest quality pads with a perfect surface for soldering.

Compatibility

This adapter PCB has been designed to be compatible with WFBGA153 eMMC chips and in theory it should be compatible with the majority of chips available on the market. However there is no telling to how a particular manufacturer might adjust it's pinout which might break compatibility. I would suggest you consult the datasheet of your chip and compare pinout before ordering the adapter, it should match the pinout indicated below:

What you get with your order

You will get 2 x PCB adapter WFBGA153 to microSD card. Flash memory or other components are not included.
