A Battery backed up Real Time Clock card for the RaspberryPi Model A, A+, B, B+, Pi2, Pi3, Pi4 and Compute Module. The temperature sensor shows the ambient temperature around the sensor, not the CPU core temperature.
Special Version with SuperCaps Fitted! When opening or closing the lid of the lapdock power is momentarily cut off, the SuperCaps provide enough power for the computer to continue to run.
Physical installation: Plugs into the GPIO pins. Fits within the footprint of the Raspberry Pi's PCB and is lower than the double USB socket 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)
Battery Capacity: Over nine years!
Real Time Clock Module with Temperature Sensor
CR1620 Battery (unfitted)
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!
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, and RISC OS software can be downloaded here.
