Pololu RC Switch with Small Low-Side MOSFET

Rating:
100% of 100
SKU: POLOLU-2802 Brand: Pololu
This RC switch converts hobby radio control pulses to digital on/off signals and has an integrated small, low-side MOSFET that allows it to drive small loads (up to around 3 A), such as lighting or small actuators. The activation threshold and direction are configurable, and a safe-start feature reduces the likelihood of unexpected activation.

The Pololu RC switch with Small Low-Side MOSFET can be used with standard hobby radio control systems for radio control switch applications or simple interface applications. Example uses 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 small loads directly. The switch also features a flyback (or freewheeling) diode across the load outputs so that you can connect a coil to them, such as a motor or relay, without any additional external components.

The board requires a 2.5–5.5 V power source supplied to VCC. The board’s MOSFET can deliver up to around 3 A with VCC at 5 V and can handle load supply voltages up to 30 V.

The RC switch measures the width of incoming RC pulses and compares it to a user-configurable threshold (with ±64 µs of hysteresis) to decide whether to turn on the MOSFET. By default, the threshold is approximately 1700 µs, with switch activation occurring above the threshold (longer pulses), but the switch has a learning mode that allows you to change the threshold and the activation direction. A safe-start feature reduces the likelihood of unexpected activation.

This compact unit measures 0.4" × 0.6" and weighs just over 0.5 g (0.02 oz) without the included header pins.

Outputs and indicator LED

The RC switch provides feedback about what state it is in via a yellow indicator LED. Status information is also provided on two output pins:

  • The GOOD pin indicates the presence of a valid RC signal (10–330 Hz pulse rate, 0.5–2.5 ms pulse width).
  • The OUT pin indicates whether the MOSFET is on.

More information about using the Pololu RC switch with Small Low-Side MOSFET can be found in the user’s guide.

Included hardware

A 12-pin 0.1" straight breakaway male header is included with the Pololu RC Switch with Small Low-Side MOSFET. The header pins can be used to connect the RC switch to perfboards or breadboards.

Other RC switches

Pololu offer an RC switch with a digital output for applications that just require a low-current digital signal and an RC switch with a medium MOSFET that can switch more current and has an integrated regulator. Pololu also offer an RC switch with a relay that can be used to control electrically isolated loads.

This product replaces item #1210. (For most applications, it can be considered a drop-in replacement for #1210.)
