About the 1u panel breakout

1u panel breakout is an open source PCB design by oresat, published on GitHub. It is a 2-layer board measuring 33 × 32 mm, with 6 components from 4 distinct parts.

Other key parts include the SCOPE_CLIP. By type, the board carries 3 ICs, 2 jumpers and 1 connector.

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

OreSat solar array designs and CAD

This repo contains the CAD for OreSat's solar modules. Part of OreSat's design is a module bus system that spans 1 - 3 U, so each array is its own 1U "panel". Oresat0, a 1U CubeSat, thus has 4 solar modules, and OreSat1, a 2U CubeSat, has 8. This approach has pretty severe drawbacks in terms of solar cell coverage area, but it's extremely flexible for having one design across a bunch of different designs. One nifty part of this design is that each 1u panel has its own true maximum power point tracker, with a software-defined MPPT algorithm. We're MPPT elitists - we eschew maximum power point…

1u panel breakout: common questions

How big is the 1u panel breakout?

The 1u panel breakout measures 33 × 32 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 1u panel breakout?

6 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the 1u panel breakout design files?

From the oresat/oresat-solar-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 1u panel breakout design in my own project?

The repository has no license, so all rights stay with oresat. Use it as a reference, and ask the author before reusing the design.
