/**
 * ARCHIM2 pin assignment
 *
 * The Archim 2.0 board requires Arduino Archim addons installed.
 *
 * - Add the following URL to Arduino IDE's Additional Board Manager URLs:
 *   https://raw.githubusercontent.com/ultimachine/ArduinoAddons/master/package_ultimachine_index.json
 *
 * - In the Arduino IDE Board Manager search for Archim and install the package.
 *
 * - Change your target board to "Archim".
