They have the software on Github and the hardware layouts (as well as additional things like Fritzing files for some boards) available through their documentation - e.g.:

- Arduino Uno: https://docs.arduino.cc/hardware/uno-rev3#resources

- Arduino Nano 33 IoT: https://docs.arduino.cc/hardware/nano-33-iot#resources
