README
README.mdPrawnblaster PCB
Provides nice panel-mountable BNC connections and ground-isolated USB for the Prawnblaster (https://github.com/labscript-suite/prawnblaster).
Loosely based on https://github.com/TU-Darmstadt-APQ/Prawnblaster_Breakout.
-Trigger input is buffered to allow 5V input without risk to Pi Pico.
-Output clocklines are buffered to drive at 5V (and avoid damage to Pi Pico from those lines floating to 5V).
-Clock input is buffered.
-Analog ADuM5000 used for 5V power isolation and Analog ADuM4160 used for USB isolation. Note that speed is fixed at high speed.
-Fits in 1U Bud box (slightly too tall, so upper panel bends slightly, but probably fine).

Questions
How big is the Prawnblaster pcb PCB?
It measures 119.4 × 54.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prawnblaster pcb use?
30 parts, built around the 74ABT245D, 74LVC1G07, 74LVC1G17Z and ADUM4160BRW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Prawnblaster pcb KiCad files?
From the carterturn/prawnblaster_pcb repository on GitHub, at the commit this page was made from: the board is prawnblaster_pcb.kicad_pcb and its schematic prawnblaster_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prawnblaster pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask carterturn before reusing the design.
