Introduction
The Alpha family of transceivers are available from Maplin, codes A58JN-A63JN.
The TX/RX are £4 each, and transceivers are £6 each.
Whichever you get, read the latest 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.
