Previously Used Peripherals
The following is the C329-UART-boardthat was used by the Clear Springs Microgravity team. The software is already written for this camera so if it fits in your requirements it is a safe bet to use. (Note: The camera is sold as a board only, the lenses can also be found on the same page but must click on a link. There are two different lenses, one for closer photos and another for photos that are further away.)
The MG811 CO2 sensor can be purchased at Futurlec.com, since this company is not located in the United States please allow very ample time for shipping (possibly multiple weeks). This CO2 sensor runs off of 6 volts but is able to be used on the NESI Board due to circuitry that boosts the voltage on the header pin.
