Board-B-sma
About the Board-B-sma
Board-B-sma is an open source PCB design by Brunner-neutrino-lab, published on GitHub. It is a 4-layer board measuring 74.8 × 149.1 mm, with 25 components from 2 distinct parts.
By type, the board carries 24 relays and 1 connector.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
Passive break-out boards that replace the (broken) iv-pulse-mux board in the Brunner-lab ETS-96-channel-IV-pulse-mux system. Instead of relay-multiplexing 24 channels onto one shared sense line, each breakout board brings every channel out to its own coaxial jack so channels can
Passive break-out boards that replace the (broken) iv-pulse-mux board in the Brunner-lab ETS-96-channel-IV-pulse-mux system. Instead of relay-multiplexing 24 channels onto one shared sense line, each breakout board brings every channel out to its own coaxial jack so channels can be biased/measured individually with external instruments.
- Mates the detector-side connector QSE-040-01-L-D-A (J5) — same socket the iv-pulse-mux board used, mating the existing QTE-040 header upstream. J5 sits on the back face (B.Cu), opposite the jacks: the detector plugs into the back, cables come off the front.…

Board-B-sma: common questions
How big is the Board-B-sma?
The Board-B-sma measures 74.8 × 149.1 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Board-B-sma?
25 components, from 2 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 Board-B-sma design files?
From the Brunner-neutrino-lab/ets-breakout repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Board-B-sma design in my own project?
The repository has no license, so all rights stay with Brunner-neutrino-lab. Use it as a reference, and ask the author before reusing the design.
