The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes,...

Torex Semiconductor's XC9141/XC9142 series of 0.8A step-up DC/DC converters come with an input–output disconnection function (load disconnection function) to prevent malfunctioning during standby, and for device functionality that enables power supply to RTC. When the output...

We came across this kickstarter campaign that features a multifunction SSD shield for Raspberry Pi 2. The shield includes SSD, WiFi, RTC w/Battery and high power USB: Pi 2 Design is excited to introduce the first offering in a new line of Embedded and Media-based I/O shields for the...

Edward Mallon @ edwardmallon.wordpress.com gives us a detailed explanation about cheap RTC modules found on ebay and other places. I built the first few beta units with the DS3231 Chronodot from Macetech (about $18 each), but I kept on stumbling across cheap RTC modules on eBay,...

mcs.uwsuper.edu has build a big LCD clock based on MSP430 mcu and DS3231 RTC clock chip. They write: The clock is built on a 4" (101 mm) LCD displays OD-103 manufactured by Orient Display. The LCD provides high contrast of digits and easy reading from a large distance. The unit runs...

Markus Gritsch posted pictures and code of his PIC24 bedside table alarm clock: Another year, another clock, but for the first time for my alarm clocks. I am not using an MSP430 but a PIC24 instead. Standby current is with 5.5 µA only slightly higher than that of my MSP430 based...
