Summary of MAX DS1339 RTC REAL TIME CLOCK FOR ARDUINO
The article compares the popular DS1307 RTC module for Arduino with the Maxim DS1339 RTC, highlighting the latter's advantages. The DS1339 supports a wider voltage range (2.97V to 5.5V), making it compatible with 3.3V projects. It also includes features such as battery backup, two alarms, and a trickle charger. The breakout board simplifies integration with Arduino projects by including all necessary components and connections.
Parts used in the MAX DS1339 RTC Real Time Clock for Arduino:
- Maxim DS1339 RTC chip
- Battery backup (coin cell or similar)
- Trickle charger components
- Breakout board PCB
- Supporting resistors and capacitors
- Connector pins for Arduino interface
The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v projects.
The Maxim DS1339 however, features a wide tolerance of voltages from 2.97V-5.5V with the typical voltage as 3.3v, a battery backup, two alarms, and a trickle charger. The breakout board here packages the DS1339 with the components and connections necessary to use with your Arduino projects easily.
