SHIM RTC is a battery backed up realtime clock and calendar add on board for Raspberry Pi that does not get in the way of other add on boards providing easy, plug and play integration and development for designs and/or applications requiring time stamps. Board communicates via I2C interface, supported by a back-up battery to ensure on-going timekeeping operation in power-down situation. Battery not included.
PiFace Real Time Clock means your Raspberry Pi always has the correct time. Furthermore, it’s that small you’ll hardly notice it’s there! You can slip it inside most cases and under, most add-on boards!
The PiFace Control and Display has been updated for the Raspberry Pi Model B+! It has a 16 character, two line display (16×2), 5 push-button tactile switches, a LED backlight, a 3-position navigation switch, and an IR Receiver. It comes with Python Libraries so you can control it, and has immediate uses in Internet Radio, Streaming media and embedded Applications.
