First tests with Arduino Uno R4 Minima

1. Identify the exact Arduino Uno R4 Minima variant, package and manufacturer documentation.
2. Identify power, ground and signal pins in the documentation. Assemble the circuit with power disconnected.
3. Follow the manufacturer’s evaluation circuit. Use a current-limited low-voltage supply and the recommended logic levels.
4. Mesurez les signaux d’entrée et de sortie. Comparez leur comportement à la fonction : carte de développement à microcontrôleur ra4m1.
