Project:Alpha transceivers
From London Hackspace Wiki
Introduction
The Alpha family of radio modules are available from Maplin, codes A58JN-A63JN.
The transmitters/receivers are £4 each, and transceivers are £6 each.
If you get one of these, read the latest TRX documentation, as the TX and RX are slightly rearranged equivalents.
Architecture
They are single chips with an external crystal and antenna that communicate up to 300m using FSK at 433, 868 or 915MHz. They have auto tuning, RSSI, and programmable gain, channel and sensitivity.
They are controllable through SPI, and provide a clock, interrupt pins and low battery indicator for use without an Arduino.
