Precision Clock Module with Memory and Temperature Sensor for 3.3V/5V IIC Interface Portable Timing Solution
The DS3231 is a low-cost, high-precision I2C real-time clock (RTC) with integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device contains a battery input to maintain timing when main power is removed. Integrated crystals improve device longevity and reduce component count in production lines. The DS3231 is available in commercial and industrial temperature ranges and is offered in a 16-pin 300-mil SO package. The RTC stores seconds, minutes, hours, day of the week, date, month, and year information. Months with fewer than 31 days are automatically adjusted at the end of the month, including leap year corrections. The clock can operate in either 24-hour or 12-hour format with AM/PM indication. It provides two programmable calendar alarms and a programmable square wave output. Address and data are transmitted serially through the I2C bidirectional bus. A temperature-compensated voltage reference and comparator circuit monitor Vcc status, detect power supply failures, provide a reset output, and automatically switch to backup power when necessary. The RST monitor pin can be used as a manual input to generate a system reset. In addition to its high timing accuracy, the DS3231 includes a digital temperature sensor accessible via the I2C interface. The accuracy of this temperature sensor is ±3°C. On-chip control circuitry enables automatic power supply detection and manages power switching between primary power and backup power (such as a low-voltage battery). If the main power supply is lost, the device continues to provide accurate timing and temperature data without performance degradation. An on-chip reset function can restart the system microprocessor when main power is restored or when the voltage returns to an acceptable range.

Please allow additional shipping time for deliveries to exceptional locations that are hard to reach, and also during busy periods such as Christmas.
All carriers deliver during normal business working hours and may require a signature on receipt, so please ensure your order is delivered to an address where someone will be available to accept it.
We do our best to ensure that the products that you order are delivered to you in full and according to your specifications. However, should you receive an incomplete order, or items different from the ones you ordered, or there is some other reason why you are not satisfied with the order, you may return the order, or any products included in the order, and receive a full refund for the items.
Certain products purchased at Fruugo cannot be returned. They fall in the following categories:
- goods which are clearly personalised or made to your specifications

- sealed goods which are not suitable for return due to health protection or hygiene reasons, if opened, eg make up, underwear, pierced jewellery
- sealed audio or video recordings or computer software, if opened
- newspapers, periodicals and magazines
Please take reasonable care of the goods whilst in your care. Any goods returned must be in a resaleable condition. They must be unworn/unused with original tags attached and in original packaging. It is your responsibility to ensure that the goods are appropriately packaged to ensure they are not damaged in return transit.

- your name,
- order number,
- the item(s) you wish to return, and
- optionally a reason for your return: unsatisfied with item, item didn't match description, damaged item, wrong item, or some other reason.
Our customer care will send you specific instructions on how to ship the return package(s) to the retailer(s). Please do not ship the return package before you receive the instructions.
Shipping products back to retailers
Goods must be returned without undue delay and in any event not later than 14 days after notifying us of your cancellation.
If you are returning products to several retailers, you should distribute the products accordingly and send the products to those retailers who shipped them to you initially.
We strongly recommend that you use registered mail (and insure any high-value packages), since neither Fruugo nor the retailer take responsibility for shipments that are lost or damaged during return transportation.
Please ensure you retain a proof of postage receipt so in the unlikely event your parcel goes missing, you will have proof you sent it.
Refunds
You will be refunded within 14 days of the retailer receiving back the goods. We will notify you by e-mail once the products reach the retailer and are accepted for return. Where a retailer has offered to collect the goods, you will be refunded within 14 days of cancelling your contract.
Unless a product or products you wish to return arrived to you damaged or faulty, you are responsible for the return transportation costs.
Providing you are returning all the products from a specific retailer, we will refund the standard shipping costs you paid for the original delivery. If you chose to pay for a non-standard delivery, we will only refund the cost of our least expensive, standard delivery.
Damaged or faulty goods
If you receive a damaged, broken, or defective product, please notify Fruugo customer care as soon as possible. Include at least the following information:
- your name,
- order number,
- name of the damaged product(s), and
- state the nature of the damage with attached photograph
We will generally instruct you to ship the damaged product back to the retailer. As soon as it reaches the retailer, they will send you a replacement product. If the replacement can't be made, or if you wish to cancel the order, you will be refunded in full. You will also be reimbursed for reasonable returns postage costs for damaged or faulty goods once we have received your postage receipt.
If the outer packaging of your order is clearly damaged on arrival, and you are suspecting that the products are damaged as well, you can either reject the delivery or accept the goods and sign for them as damaged. In both instances, please notify Fruugo customer care as soon as possible.

If you refuse to accept delivery of all or part of your order (where the products or packaging do not appear to be damaged or defective) you will be responsible for the postage charges.
