Introduction

The Alpha Modules are extremely cost effective but high

performance radio modules. Supplied in a miniature Surface mount package these modules can

Transmit/Receive at upto 115Kbps at upto 300m range.

Operating at 2-5V, both transmitter and receiver monitor their battery voltage and can sleep with very low

standby current. The modules can wake intermittently and provide direct control outputs to a

microcontroller, ideally suited to battery applications. (Especially receivers!)

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.
