If cost is an issue, the below might be of interest. If one lives in a remote jungle, then other factors will probably interfere with even a regular arduino.
Here is one cheaper... $9.50
http://www.electrodragon.com/?product=arduino-pro-mini-328-5v16mhz
I like to use stackable headers on my projects and I buy the Pro mini's because they are smaller than a standard 28 pin dip... Same size as a basic stamp with 10 extra useful pins
And here is a picture on one of the breadboards W/ Uno cable connector and a plugin PSU with 3V3 or 5V on either rail or both rails... takes a USB connector (for power only) or a
2.1 mm barrel connector for an external PSU (Wall Wart) Liudr sells the cab;e/shield/breadboard header... From Either Dipmicro or Inmojo for $18.95... The PSU is $2.89 from Ebay
{Edit} The little board to the left of the Pro Mini is an USB to ttl converter also purchased from Electrodragon... I use it for a lot of different things besides the Pro Mini's.
