DS1339 RTC Breakout Board is a RTC breakout board from Upbeat Labs based on the DS1339 RTC from Maxim
The board is designed to be breadboard friendly, and also capable of being plugged in directly to an Arduino or a Raspberry Pi by its innovative dual headers design.
Environmentally friendly and high-quality ENIG finish and lead-free solder.
It includes 2 mounting holes for attaching to an enclosure if desired.
The DS1339 contains two time of day/date alarms that can raise an interrupt via the SQW/INT pin. It can also generate a square-wave output at the following frequencies:
1Hz 4.096kHz 8.192kHz 32.768kHz
The DS1339 also includes a trickle charger circuit, that can be enabled via the registers. This breakout board is meant to be used with a coin-cell battery (non-rechargeable) however, if you are interested, let me know and I'll add the ability the incorporate a super-cap or rechargeable battery either here or on another board! If you are adventurous, you can always hook it up to this board by accessing the connections to Vbat and GND!
DS1339 RTC is tolerant of a wide range of voltages, so you can use it with any 5v or 3.3v MCU without need for level shifting.
I worked on an Arduino-based Bluetooth LE (BLE) logger for TI's SensorTag - the Arduino Pro Mini would connect to the Sensor Tag as a BLE master and read the data and log it to an SD card. For that, I needed an RTC that worked with 3.3v, and an alarm to perhaps use with sleep modes to reduce power consumption, and settled on the DS1339 chip as perfect for my needs. I ended up creating a breakout board a while back and writing about it on Instructables (see link below)
I have now decided to bring it up to date with all SMD components and an innovative dual header design that is also breadboard friendly - you can take this and plug it directly into your Arduino or Raspberry Pi and start using it without any breadboard or jumper wires (well, one jumper wire to Pin 2 of Arduino if you want to use its alarm functionality)
It comes with an Arduino library (see GitHub link below), and can also be used with the Raspberry Pi directly by using the rtc-ds1307 module (which has the same register format as the DS1339 for the date/time portion). You can easily find instructions on how to enable an RTC on the Raspberry Pi via many links online.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
Upbeat Labs designs and creates innovative products for the Maker Community.
The first product is Dr. Wattson, an Energy Monitoring Breakout Board for Arduino, Raspberry Pi and other Maker-friendly MCUs. Integrating calibrated, quality energy measurements into your next project is now a breeze!
I have also created a laser cut acrylic enclosure to put Dr. Wattson in - this helps to isolate the high voltage components that are hooked up to Dr. Wattson, so only safe digital signals and wires are accessible outside for hookup to your micro-controller.
The DS1339 RTC Breakout Board is 3.3/5v friendly and can be used directly with Raspberry Pi or Arduino as plug-in-play with an innovative double header design, and is breadboard friendly too.
The Latching Relay Breakout Board has a pair of RT314F05 bistable 2-coil latching relays that can switch up to 16A @ 250VAC using 5VDC. Use it where you want to minimize power consumption as it doesn't require continuous current to maintain its state.
