This is a Real Time Clock and Calendar module with the additional facility to generate hardware alarms. Up to two alarm times can be programmed into the clock and are signalled via the Pi's GPIO4

Alternatively, the module can be programmed to send a clock frequency to GPIO4. This can be 1Hz, 4.096kHz, 8.192kHz and 32.768kHz

Each module will be fully tested prior to despatch. Installation details and software will be available for download as a PDF document

This module is based on the MCP79410 RTCC ic from Microchip. The main features are as follows:

  • Very small footprint - well within the outline of the Pi
  • Fits directly to GPIO port
  • Shaped PCB allows access to remaining pins of GPIO port
  • Communication via I2C
  • Battery backup (Battery NOT supplied*)
  • Calendar as well as time, i.e.: Year, Month, Date, Day; Hours, Minutes, Seconds
  • Up to two programmable alarm times - output to GPIO4
  • Power up/down timestamps

Each module will be fully tested prior to despatch. Installation details and software will be available for download as a PDF document from the web address included with the module.

*Please note that due to shipping restrictions, I am unable to supply the BR1225 cell required for the battery back-up.
