Introduction
The Alpha Modules are extremely cost effective but high performance radio modules. Supplied in a
miniature Surface mount package this Transceiver module can Transmit/Receive at upto 115Kbps at a
maximum of 300m.
Operating at 2-5V, the module monitors its battery voltage and can sleep with very low standby current.
The module can wake intermittently and provide direct control outputs to a microcontroller making it
ideally suited to battery applications.
These Modules will suit one to one multi-node wireless links in applications including car and building
security, POS and inventory tracking, remote process monitoring.
