PowerSwitch
About the PowerSwitch PCB
PowerSwitch is an open source PCB design by iNavFlight, published on GitHub. It is a 2-layer board measuring 14.9 × 7.5 mm, with 9 components from 8 distinct parts.
By type, the board carries 4 resistors, 3 connectors and 2 transistors.
From the project
High side power switch that can be controlled by the flight controller used PINIO.
High side power switch that can be controlled by the flight controller used PINIO.
Switching on the high side (instead of the simpler low side) is useful for devices that must stay at exactly the same ground potential (e.g. camera and VTX).

PowerSwitch: common questions
How big is the PowerSwitch PCB?
The PowerSwitch measures 14.9 × 7.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PowerSwitch?
9 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the PowerSwitch design files?
From the iNavFlight/hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the PowerSwitch design in my own project?
The repository has no license, so all rights stay with iNavFlight. Use it as a reference, and ask the author before reusing the design.
