The [http://www.rfsolutions.co.uk/acatalog/FM_Radio_Modules.html Alpha family] of transceivers are available from Maplin, [http://www.maplin.co.uk/module.aspx?moduleno=267236 codes A58JN-A63JN]. | The [http://www.rfsolutions.co.uk/acatalog/FM_Radio_Modules.html Alpha family] of transceivers are available from Maplin, [http://www.maplin.co.uk/module.aspx?moduleno=267236 codes A58JN-A63JN]. | ||
The TX/RX are £4 each, and transceivers are £6 each. | The [http://www.rfsolutions.co.uk/acatalog/DS-ALPHATX-4.pdf TX/RX] are £4 each, and [http://www.rfsolutions.co.uk/acatalog/DS-ALPHA-TRX-5.pdf transceivers] are £6 each. | ||
Whichever you get, read the latest TRX [http://www.rfsolutions.co.uk/acatalog/DS-ALPHA-TRX-6.pdf TRX documentation], as the TX and RX are slightly rearranged equivalents. | |||
== Architecture == | |||
They are single chips with an external crystal which transmit FSK at 433, 868 or 915MHz. They have auto tuning, RSSI, gain and can communicate up to 300m. | |||
They are controllable through SPI, and provide a clock, interrupt pins and low battery indicator for use without an Arduino. | |||
