I need to log data from 6 sensors. Is there a hardware limit on the number of channels, or is this programmable?

The Arduino Uno R3 has 6 analog inputs the can convert a voltage signal into a binary number the the microcontroller can make use of. You also have 14 digital IO pins that can be used to determine if a switch is on or off. The Uno can also receive digital data from a large number of sensors using I2C, OneWire and SPI protocols. So the number of sensors could approach 100 and should be writable to the SD card.

Mine did not come with a battery. What battery does it use?

Lithium cell CR1220 3V with the + showing.

Does it work with a Mega 2560 ?

yes, I use it with 2560, plugs into the 2560
