Tips

Ensure your external power supply is within 7-28V DC and properly regulated to avoid damage. For high-current devices like relays or solenoids, use external drivers as digital outputs are limited to 20mA per pin. Update firmware regularly to benefit from the latest features and compatibility improvements.
