The Pololu RC switch with digital output can be used with standard hobby radio control systems for radio control switch applications or simple interface applications. Example applications include converting extra RC receiver or servo controller outputs to simple high/low signals that can control LEDs or MOSFETs or relays and connecting RC systems to microcontroller projects that do not have the necessary resources for decoding the RC interface. Two outputs indicate the presence of a valid signal and whether the switch is on or off. This compact unit measures a mere 0.4" x 0.4" and weighs just 0.3 g (0.01 oz).
