Questions
How big is the Transimpedance Amplifier PCB?
It measures 66 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Transimpedance Amplifier use?
21 parts, built around the LMC6482IN and TLE2425CD. 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 Transimpedance Amplifier KiCad files?
From the Tanmayeers/Projects repository on GitHub, at the commit this page was made from: the board is PCB - Projects/Transimpedance Amplifier/TA.kicad_pcb and its schematic PCB - Projects/ESP32/ESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Transimpedance Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tanmayeers before reusing the design.
