EnviroDIY Mayfly Data Logger Board and Starter Kit (Pack of 5)


5 EnviroDIY Mayfly Data Logger Starter Kits, each including:

    • 1 EnviroDIY Mayfly Data Logger Board (this is the latest version 0.5b, released Fall 2017)
    • 1 waterproof enclosure with clear lid (screws and gasket included)
    • 0.5 watt solar panel with JST connector
    • Mayfly microSD connector board
    • 8GB microSD memory card with SD-size adapter
    • MicroUSB interface cable (1-meter long)
    • 2 Grove cables (20cm long)

Single unit purchases can be made on Amazon.

The Mayfly Data Logger is a powerful, user-programmable microprocessor board that can be easily programmed with several popular IDE software programs. It features the ATmega1284p processor, which is much more powerful than the 328p chip found on most other boards. It has 4 times more flash memory for sketches, 8 times more RAM, and almost twice as many input pins as standard boards.

The Mayfly board can be powered by a 3.7v lithium polymer (lipo) battery (not supplied) or through the microUSB port. Programming can be done through the microUSB port or via the FTDI header.

You will need a CR1220 button cell lithium battery (not supplied) in order for the RTC to retain the time after the power has been removed. More information and tutorials about the board and kit can be found on the EnviroDIY website.
