About the Switch PCB

Switch is an open source PCB design by gongminmin, published on GitHub under the MIT license. It is a 2-layer board measuring 85.1 × 30.5 mm, with 38 components from 19 distinct parts.

Other key parts include the PC817, B1212S and B1205S. By type, the board carries 13 resistors, 6 connectors, 5 ICs, 4 diodes, 3 transistors and 3 capacitors.

From the project

A preliminary design of a plasma engine for spacecraft propulsion

In Star Trek universe, impulse drive is a propulsion system of spacecrafts for interplanetary travel. This project is trying to design a real-world impulse drive. The basic characteristics of this engine are

Electric propulsion Large thrust Long specific impulse No or little moving parts Good scalability Low cost

We'd like to make it easy to implement, so people can build it as a hobby project.
