It can be used to make connections between devices with 0.1" 3-pin male headers, such as between RC servo controllers or RC receivers and motor controllers with an RC interface. It can also be a convenient way to connect various 3-pin sensors to a robot controller. The cable’s conductors each consist of 60 strands, making it more flexible than standard servo cables. ## Pricing - **Price:** $7.75 (inc GST) — $7.05 AUD, exc GST - **Quantity discounts:** 10+ $6.76 (exc GST) · 25+ $6.55 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 20 and Aug 24. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-780:1` (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-780:1.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 This servo extension cable has [female JR connectors](https://core-electronics.com.au/jr-connector-pack-female.html) on both ends, so it can be used to make connections between devices with 0.1" 3-pin male headers, such as between [RC servo controllers](https://core-electronics.com.au/breakout-boards-and-modules/motor-drivers-controllers/servo-controllers.html) or RC receivers and [motor controllers](https://core-electronics.com.au/components/motors/dc-motors.html) with an [RC interface](https://core-electronics.com.au/category/53/rc-interface). The cable’s connectors are commonly found on [RC servo](https://core-electronics.com.au/category/23/rc-servos) leads and work with both [male JR](https://core-electronics.com.au/jr-connector-pack-male.html) and [male Futaba J](https://core-electronics.com.au/futaba-j-connector-pack-male.html) connectors. They have gold-flashed contacts on a 0.1" spacing and are joined by 22-AWG, 60-strand wires that make this cable more flexible than standard servo cables. **Note:** The cable’s female connectors are the same as what is found on most generic servos and fits nicely with [0.1" male headers](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html), but is often referred to as “male” in the RC hobby industry. The picture below shows the cable connectors labeled with Pololu's gender convention. | [![](https://core-electronics.com.au/attachments/localcontent/0J3404_186386d2bf7.jpg)](https://core-electronics.com.au/attachments/localcontent/0J3404_1442467d1f2.jpg) | |---| | Female “JR”-style connector commonly found on servo cables (often referred to as “male” in the RC hobby industry). | These female-to-female cables are available in two styles: **[flat](https://core-electronics.com.au/servo-extension-cable-12-female-female.html)**, with wires stuck together side by side, and **[twisted](https://core-electronics.com.au/twisted-servo-extension-cable-12-female-female.html)**, with wires twisted around each other to decrease electromagnetic interference (EMI).
