Spi flash adapter v1
About the Spi flash adapter v1 PCB
Spi flash adapter v1 is an open source PCB design by Spectating101, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 50 mm, with 18 components from 10 distinct parts.
Other key parts include the TXU0304PWR, W25Q128JWSIQ and TLV75518PDBVR. By type, the board carries 7 resistors, 6 capacitors, 3 ICs, 1 connector and 1 jumper.
From the project
Auditable hardware bring-up: donor → KiCad carrier + DRC + bench gates → PROJECT_PACKAGE. Seeking 3 design partners.
This directory is the first complete Hardware Splicer reference design for the frozen 3.3 V-host to 1.8 V W25Q128JW case. It contains an editable KiCad 9 schematic, a routed two-layer PCB, an exact BOM, a machine-readable evidence/authority manifest, and scripts that regenerate, verify, and package the work without an external design contractor.
The current artifact is a bounded pre-fabrication result. It is internally consistent and reviewable, but it is not fabrication-authorized, power-on-authorized, or physically validated.
