Questions
How big is the Labamp ia PCB?
It measures 55 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Labamp ia use?
37 parts, built around the THS4521ID, M2.5 and BAT54S. 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 Labamp ia KiCad files?
From the bernienor/labamp repository on GitHub, at the commit this page was made from: the board is labamp_IA/labamp_ia.kicad_pcb and its schematic labamp_FullDiff/labamp_FullDiff.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Labamp ia design in my own project?
Its repository states no licence, so its author keeps all rights: ask bernienor before reusing the design.
