About the Bay card PCB

Bay card is an open source PCB design by dmz006, published on GitHub under the Custom license license. It is a 4-layer board measuring 45 × 46 mm, with 38 components from 17 distinct parts.

Other key parts include the ASM1153E. By type, the board carries 20 capacitors, 8 resistors, 4 transistors, 2 fuses, 1 IC and 1 crystal.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Standalone four-bay (plus M.2) NIST 800-88 disk sanitizer: Raspberry Pi CM5 carrier board, Python service, 3D-printed enclosure

Two KiCad 9 projects, both generated from tools/design.py (see ../docs/LAYOUT-REVIEW.md for how, and for what a layout engineer must check). Design intent: ../docs/ARCHITECTURE.md section 3. Parts: ../docs/BOM.md. Regenerate and route commands: ../docs/USAGE.md.

More views and the assembled unit: ../docs/RENDERS.md. KiCad's own 3D views are in renders/, one image per layer in renders/layers/ (F.Cu, In1 to In4, B.Cu, assembly-top, assembly-bottom, mask), schematic sheets in renders/schematic/.

Bay card: common questions

How big is the Bay card PCB?

The Bay card measures 45 × 46 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Bay card?

38 components, from 17 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 Bay card design files?

From the dmz006/brain-drain 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 Bay card design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.
