The RF315 and RFOB cards let you receive packets from your keychain 315 MHz or 434 MHz transmitter. Both cards take an RF module similar to the Sparkfun WRL-10532 or the WRL-10533. The RF315 card has a built-in 315 MHz antenna while the RFOB card has an SMA antenna connector. The RF315 card is convenient while the RFOB card lets you place the antenna where you choose.
