About the Film capacitors PCB
Film capacitors is an open source PCB design by owntech-foundation, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 129 × 32 mm, with 7 components from 2 distinct parts.
By type, the board carries 4 connectors and 3 capacitors.
It belongs with the power & battery designs in this gallery.
From the project
A repository to do collective work on an open source micro-inverter.
- Having the first open source PV micro-inverter - Finally a design easy to repair that is no longer a black box - Redeem your data sovereignty, you will no longer depend on a proprietary cloud to follow your solar production and consumption.
- This project is propulsed by its community. - The collective work generated is meant to remain open. - Design files are made with open source software - Namely kiCAD. - Mechanical interfaces and components are modeled using FreeCAD. - Simulation files use ngSpice.
