This is sold as a kit. It requires only moderate soldering skills and consists of only a few components. With the exception of one small part, everything is 'thru hole' soldering making it very easy to put together. This Receiver board is generic so it works with both the bluetooth radio module and the Xbee for use with the Protothrottle. It can also work with Airwire, however I do not have the firmware for that finished yet.
NOTE this DOES NOT include the network module. You must purchase that separately. This board will accept both the Bluetooth Module and Xbee Network Modules.
