Inbuilt RTC for Timekeeping
The onboard Renesas RA4M1 microcontroller is equipped with an inbuilt Real-Time Clock (RTC), allowing the board to keep track of time. This feature ensures accurate timekeeping and can be utilized in various time-sensitive applications.
Voltage RTC Pin
While both versions of the R4 board have the inbuilt RTC function, the R4 WiFi version also comes with an additional Voltage RTC pin. This pin enables the onboard RTC to continue running even when the power supply is cut off. To activate this feature, a voltage between 1.6 to 3.6 V needs to be applied to the pin.
Power Options
The Arduino ESP32 S3 Mini can be powered in multiple ways. Users have the option of using the barrel jack or Vin pin, with a voltage range of 6 to 24 volts. Alternatively, a USB C cable with a 5 V supply can be used. It is important to note that the ESP32 S3 Mini requires 3.3 volts, which is handled by the onboard voltage regulator. When powering from the ESP header, it is crucial to ensure that the voltage does not exceed 3.3 V.
Quality and Authenticity
Arduino boards are known for their superior build quality, proper labels, and clear markings. Unlike cheap clones, original Arduino boards deliver reliability and accuracy. This can be observed in the 13 digital pins, clearly marked both inside and outside the header pins, of which 6 are PWM pins.
Overall, the Arduino ESP32 S3 Mini is an impressive dev board that offers a wide range of features and functionalities. From WiFi and Bluetooth capabilities to an inbuilt LED matrix and RTC, this board is a valuable tool for electronics enthusiasts and IoT developers.
