Overview

OBCV7 is an open-source printed circuit board by UChicago-Space-Program, from the UChicago-Space-Program/pulse-hardware repository on GitHub. It is a 4-layer board of 90.3 × 95.9 mm with 51 parts on 175 nets, routed with 510 tracks and 23 vias.

It is built around the ADM3485EARZ, TCAN337GD and MAX706ARESA+T, with the BAT54CW, EG1215AA and SIT1533AI-H4-DCC-32.768E among its other parts. Its parts include 14 capacitors, 12 resistors, 6 ICs, 3 diodes and 1 switch.

README

Template for PC104 to use for the boards. Keep in mind that the four holes on the board are througholes and it is important that all of the boards have the same distance for their throughole parts.

We should also adhere to having 2.54mm headers that are spaced at a certain (non-disclosed) distance from any holes

Questions

How big is the OBCV7 PCB?

It measures 90.3 × 95.9 mm and has 4 copper layers, 1.6 mm thick.

What parts does the OBCV7 use?

51 parts, built around the ADM3485EARZ, TCAN337GD, MAX706ARESA+T and BAT54CW. 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 OBCV7 KiCad files?

From the UChicago-Space-Program/pulse-hardware repository on GitHub, at the commit this page was made from: the board is flight-subsystem-designs/cdh/flight-computer/OBCV7/OBCV7.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the OBCV7 design in my own project?

Its repository states no licence, so its author keeps all rights: ask UChicago-Space-Program before reusing the design.
