Main components
1README
README.mdLEDTester
Just a simple LED tester that lets you test you LEDs from 0.1mA to (almost) 50 mA. There are two versions of it:
- One uses pushbuttons to control the current
- One uses a 16 position coded switch

Questions
How big is the LEDTesterV1 PCB?
It measures 85 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LEDTesterV1 use?
32 parts, built around the LMV722M. 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 LEDTesterV1 KiCad files?
From the BurningElectronics/LEDTester repository on GitHub, at the commit this page was made from: the board is V1_Pushbuttons/Hardware/LEDTesterV1/LEDTesterV1.kicad_pcb and its schematic V1_Pushbuttons/Hardware/LEDTesterV1/LEDTesterV1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LEDTesterV1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
