Pololu RC Switch with Small Low-Side MOSFET

Vendor's Description: 

This tiny board converts hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal (10-100 Hz pulse rate, 0.5-2.5 ms pulse width), and the other output indicates whether the pulse width is above or below the 1.6 ms threshold (with ±0.1 ms hysteresis). An integrated small, low-side MOSFET can be used to drive small loads (up to around 3 A), such as a relay, when the switch is on.
