One output indicates the presence of a valid RC signal, and the other indicates whether the switch is active. The activation threshold and direction are configurable, and a safe-start feature reduces the likelihood of unexpected activation. ## Pricing - **Price:** $12.60 (inc GST) — $11.45 AUD, exc GST - **Quantity discounts:** 10+ $11.00 (exc GST) · 25+ $10.65 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 31 and Sep 01. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-2801:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-2801:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description | [![](https://core-electronics.com.au/attachments/localcontent/0J4856_203397e0ad2.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4856_11413ccea05.jpg) | |---| | Pololu RC Switch with Digital Output, bottom view with dimensions. | | [![](https://core-electronics.com.au/attachments/localcontent/0J4852_23545987351.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4852_18716929611.png) | |---| 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. For example, this module can be used to convert unused RC receiver or servo controller channels to simple high/low signals that can control LEDs, MOSFETs, or relays, or it can serve as a simple interface between RC systems and microcontrollers that do not have the necessary resources for decoding hobby RC servo pulses. Two digital outputs indicate the presence of a valid signal and whether the switch is on or off. The board requires a 2.5–5.5 V power source supplied to VCC. The board can be powered by whatever digital system is reading the output, or it can be powered from the RC receiver if you bridge the surface-mount jumper on the bottom of the board that connects VRC to VCC. 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 the output. 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" × 0.4" and weighs 0.3 g (0.01 oz) without the included header pins. | [![](https://core-electronics.com.au/attachments/localcontent/0J4853_141892a888f.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4853_43996bbc795.png) | |---| | Typical wiring diagram for the Pololu RC Switch with Digital Output. | **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 is the main output of the board and indicates whether the switch is active. Each of the these outputs can source or sink up to 25 mA. More information about using the Pololu RC switch with Digital Output can be found in the user’s guide. **Included hardware** A 7-pin [0.1" straight breakaway male header](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) is included with the Pololu RC switch with Digital Output. The header pins can be used to connect the RC switch to perfboards or [breadboards](https://core-electronics.com.au/prototyping/breadboards.html), or you can solder wires directly to the board for the most compact installation. | \| [![](https://core-electronics.com.au/attachments/localcontent/0J4854_188005cd488.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4854_206925e7508.jpg) \| \|---\| \| Pololu RC Switch with Digital Output with included hardware. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J4855_218232559a9.jpg)](https://core-electronics.com.au/attachments/localcontent/0J4855_30455982354.jpg) \| \|---\|---\| \| Pololu RC Switch with Digital Output on a breadboard. \| | |---| **Other RC switches** Pololu offer two versions of this switch with integrated MOSFETS that can switch loads directly: [RC switch with a small MOSFET](https://core-electronics.com.au/pololu-rc-switch-with-small-low-side-mosfet.html) and [RC switch with a medium MOSFET](https://core-electronics.com.au/pololu-rc-switch-with-medium-low-side-mosfet.html) (the latter of which also has an integrated voltage regulator).
