Description
The Atmel AT86RF401 Smart RF Microtransmitter is a highly integrated, low-cost RF
transmitter, combined with an AVR RISC microcontroller. It requires only a crystal, a
single LiMnO
2
coin cell (CR2032 or similar), three capacitors, an inductor and a tuned-
loop antenna to implement a complete on-off keyed (OOF) wireless RF data
transmitter.
