From the project
Proyecto Final para el armado de un nanoSat
Este documento resume las placas, elementos estructurales, componentes externos, cableado y tornillería necesarios para el armado de la plataforma PocketQube.
Link de la wiki donde se explica todo sobre el proyecto:
- 4 integrados en las pqlatboard - 1 integrado en la pqbotboard - 1 en la PQMagYBoard`
Los magnetorquers integrados en las placas se forman mediante pistas/bobinas de cobre del propio PCB, por lo que no se compran como componentes independientes.

PQ EPS: common questions
How big is the PQ EPS PCB?
The PQ EPS measures 40 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the PQ EPS?
83 components, from 83 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 PQ EPS design files?
From the abelwu2001/Picosat-Pocketcube-UTN-FRC-2026 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 PQ EPS design in my own project?
The repository has no license, so all rights stay with abelwu2001. Use it as a reference, and ask the author before reusing the design.
