Base
About the Base PCB
Base is an open source PCB design by alxgmpr, published on GitHub. It is a 4-layer board measuring 27.8 × 61.4 mm, with 6 components from 5 distinct parts.
By type, the board carries 2 connectors, 2 capacitors and 2 resistors.
It belongs with the usb & debug tools designs in this gallery.
From the project
BGA-67 NAND flash to DIP48 adapter for XGecu programmers, split across a flash carrier and a DIP48 base board
Reusable bridge between the Google Home Mini's VFBGA67 NAND lands and a commercial XGecu BGA-to-DIP48 socket adapter.
The architecture is intentionally asymmetric:
The actual NAND remains clamped in the XGecu adapter. That adapter/NAND assembly moves between the programmer and board B. Board A is a permanent, chipless interposer soldered to the Google motherboard; it has no NAND package and no sacrificial memory.
Base bill of materials (BOM)
6 components, 5 distinct parts — part numbers from the project's BOM.

Base: common questions
How big is the Base PCB?
The Base measures 27.8 × 61.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Base?
6 components, from 5 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Base design files?
From the alxgmpr/bga67-to-dip48 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Base design in my own project?
The repository has no license, so all rights stay with alxgmpr. Use it as a reference, and ask the author before reusing the design.
