Specifications:

Transmitter module uses SAW stable frequency, small temperature excursion, even no excursion with hand touching, which can still guarantee the stable performance in the environment of vibration and big temperature change. The low price allows it to be the complete substitute of LC oscillating circui. Frequency error is generally within +/-75KHz, not like LC oscillating circui of which the error is around +/-500KHz, so that guarantee the reliability. Under the normal conditions, quiescent current is very small. Wide operating voltage range between DC3~12V; Factory setting frequency is normally 315MHz/433Mhz, the frequency can be adjusted from 260MHz to 433MHz in case of special requirement.
