Description:
Power Control, Real Time Clock & Temperature Sensor Module for the Raspberry Pi.

Two on/off inputs
Three on/off outputs
On board PIC controlled via I2C (specification here.)

Connect the on board PICs power input to an always on power e.g. an Pico, MiniITX or ATX's 'standby power' and then connect a momentary or latching On/Off switch to the board for power control like on a standard PC.
Support for 'Soft Off'[1]
Reset button support for Rev1 & Rev 2 Raspberry Pi's
Force off option.

Front miniITX/ATX case Power-On LED support
Front miniITX/ATX case Filing system access (eg. HDD) One/Three colour LED support[2]

[1] Soft Off support is coming soon to RISC OS on the Raspberry Pi. We are looking for a Linux programmer to help implement Debian support. If interested please email chris@cjemicros.co.uk

[2] Filing system access LED support available NOW for RISC OS on the Raspberry Pi.
Including option for red LED for Write and green LED flashes for Read if a two colour LED is connected. We are looking for a Linux programmer to help implement Debian support. If interested please email chris@cjemicros.co.uk

Battery backed up Real Time Clock card and Temperature Sensor also included.

Physical installation: Plugs into the GPIO pins. Fits within the footprint of the Raspberry Pi's PCB and is lower than the USB sockets so should fit into almost any case. Full fitting instructions are on our main website.

Real Time Clock chip: Maxim DS1338
Temperature Sensor: MCP9801 (LM75 compatible)
Cell (Battery): CR1620
Crystal Accuracy: 20ppm (better than 1 minute a month)

Real Time Clock Module with Temperature Sensor
CR1620 Battery (unfitted)
Fitting Instructions

Software Support:
Raspbian "wheezy" now supports the Real Time Clock (see fitting instructions above for how to enable this).
The official RISC OS downloads include Real Time Clock support now!

We are current searching for Linux software for the temperature sensor, the MCP9801 is a commonly used chip that is software compatible with many other I2C temperature sensors. The temperature sensor hardware has been tested using RISC OS!
