The Kits are NOT different, you can stick one of the boards just on to the interface of the -001 board. Together with the Kits I mentioned (they are PSoC1s) come a couple of example-projects up to a weather-station. The interesting points are: the boards transmit to a usb-interfaced master which talks to a program on your PC. There is a network-software for the boards which makes it really easy to have more than one of them connected via RF to the master.
When needing examples, download the installation files for the Kits and have a look at the examples.
