QPoint

This is a medicore BJT measurement device. It does not use SMUs, negative voltages, and other fancy things. The focus of this project was to learn analog circuits and use them in something (hopefully fun).

Questions

How big is the QPoint PCB?

It measures 78 × 84 mm and has 2 copper layers, 1.6 mm thick.

What parts does the QPoint use?

146 parts, built around the MCP6022-I/P, TPS61099DRV, TS5A3359DCU and 1N5819HW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the QPoint KiCad files?

From the lysolaka/QPoint repository on GitHub, at the commit this page was made from: the board is QPoint/QPoint.kicad_pcb and its schematic QPoint/QPoint.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the QPoint design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
