Questions

How big is the ArdTester PCB?

It measures 142.2 × 125.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ArdTester use?

66 parts, built around the ATMEGA328P-PU, ARDUINO UNO R3 and AMS1117-5.0. 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 ArdTester KiCad files?

From the jonsag/miscArduino repository on GitHub, at the commit this page was made from: the board is ardTester/ardTester.kicad_pcb and its schematic ATmega328-test-rig/ATmega328-test-rig.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ArdTester design in my own project?

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