Questions

How big is the TransimpedianceAmplifierV2 PCB?

It measures 96.5 × 48.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the TransimpedianceAmplifierV2 use?

115 parts, built around the MAX44246ASA+. 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 TransimpedianceAmplifierV2 KiCad files?

From the freudenthal/TransimpedanceAmplifier repository on GitHub, at the commit this page was made from: the board is TransimpedianceAmplifierV2.kicad_pcb and its schematic OutputOffset.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the TransimpedianceAmplifierV2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask freudenthal before reusing the design.
