Note: For use with the range of Toadstool prototyping boards:

• Toadstool Mega328

Let your Toadstool Project Tell the Time

Simply connect this RTC module to the standard header on your Toadstool and your project can keep time. The RTC module is self-contained with all the supporting components you need to keep track of time. It includes a backup battery holder (coin cell battery not included).

The Specs

The RTC IC on the breakout is the Microchip MCP79400. It connects using an I2C(TWI) interface, and:

• Operates from voltages as low as 1.8V
• Has automatic battery switch-over if power fails (with timestamps)
• Has 2 Alarms

What makes it special?

Quick and easy prototyping, without having to add those extra wires and resistors to your project.

A sample project for the Toadstool Mega328 is on our Github site, to get you up and running fast.

Note: In order to protect the header pins, the board is shipped without them soldered on.

Due to shipping restrictions, the coin cell backup battery is not included
