Servo horns and associated hardware are included. Key specs at 6 V: 0.08 sec/60°, 21 oz-in (1.5 kg-cm), 9.0 g. ## Pricing - **Price:** $14.55 (inc GST) — $13.23 AUD, exc GST - **Quantity discounts:** 10+ $12.70 (exc GST) · 25+ $12.30 (exc GST) ## Availability & dispatch - Out of stock — the product page offers email notification when it returns. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-1050:1` (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-1050:1.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/0J3877_1275370cf36.jpg)](https://core-electronics.com.au/attachments/localcontent/0J3877_105166faa8c.jpg) \| \|---\| \| An example of hardware included with the Power HD micro servo HD-1900A.

The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. Mounting screws and an assortment of servo horns is included with this servo. The picture above shows an example of this included hardware (hardware might vary). You can find more information about this servo under the specifications tab and in its datasheet (187k pdf). This servo is very similar in size, weight, and performance to the [FEETECH FS90 micro servo](https://core-electronics.com.au/feetech-fs90-micro-servo.html) and [FEETECH FS90R micro continuous rotation servo](https://core-electronics.com.au/feetech-fs90r-micro-continuous-rotation-servo.html), the latter of which offers continuous rotation speed control as opposed to limited-range position control. Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears. **People often buy this product together with:** | [![Shrouded Box Header: 2×3-Pin, 0.100" (2.54 mm) Male](https://core-electronics.com.au/attachments/localcontent/0J680_4045552c48.jpg)](https://core-electronics.com.au/shrouded-box-header-2x3-pin-0-100-2-54-mm-male.html) | [Shrouded Box Header: 2×3-Pin, 0.100" (2.54 mm) Male](https://core-electronics.com.au/shrouded-box-header-2x3-pin-0-100-2-54-mm-male.html) | |---|---| | [![0.100" (2.54 mm) Breakaway Male Header: 1×40-Pin, Straight, Black](https://core-electronics.com.au/attachments/localcontent/0J6370_2747ad6d8f.jpg)](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) | [0.100" (2.54 mm) Breakaway Male Header: 1×40-Pin, Straight, Black](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) | |---|---| | [![6-Conductor Ribbon Cable with IDC Connectors 12"](https://core-electronics.com.au/attachments/localcontent/0J745_31865fa1d5.jpg)](https://core-electronics.com.au/6-conductor-ribbon-cable-with-idc-connectors-12.html) | [6-Conductor Ribbon Cable with IDC Connectors 12"](https://core-electronics.com.au/6-conductor-ribbon-cable-with-idc-connectors-12.html) | |---|---| **Dimensions** | Size: | 22.9 x 12.0 x 27.3 mm | |---|---| | Weight: | 9 g | **General specifications** | Digital?: | N | |---|---| | No-load current @ 6V: | 140 mA | | Stall current @ 6V: | 830 mA | | Speed @ 6V: | 0.08 sec/60° | | Stall torque @ 6V: | 1.5 kg·cm | | Speed @ 4.8V: | 0.11 sec/60° | | Stall torque @ 4.8V: | 1.2 kg·cm | | Hardware included?: | Y | | Lead length: | 6 in | **File downloads** - **Datasheet for the Power HD micro servo HD-1900A (187k pdf)** ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/p/o/power_hd_micro_servo_hd_1900a__pololu_1050__00.jpg)
