RC Switch with Medium Low-Side MOSFET

SKU : RCSwML-SMOSFET

Overview

The Pololu RC switch with medium low-side MOSFET 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 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, and an integrated low-side MOSFET turns on when the switch is on, allowing the board to drive moderate loads directly. The switch also features a flyback (or freewheeling) diode across the drive outputs so that you can connect a coil to them, such as a motor or relay, without any additional external components.

This compact unit measures a mere 0.6" x 0.8" and weighs just over a gram (0.04 oz) without the included header pins.

We offer a version of this RC switch without a MOSFET for applications that just require a low-current digital signal and a version with a small-sized MOSFET for applications that only need to switch a few amps.
