## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3105-0201-0040:1` (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/GB-3105-0201-0040:1.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)

## Description

The 2x40A Motor Controller is the peanut butter if the [goBILDA® 20V Smart Dock](https://www.gobilda.com/gobilda-smart-dock-for-20v-battery-dewalt-20v-compatible/) is the jelly! This 2-channel controller is ready to proportionally control the speed and direction of up to two [Saturn Planetary Gear Motors](https://www.gobilda.com/saturn-planetary-gear-motors/) per channel. Add the [20V Battery](https://core-electronics.com.au/20v-6ah-li-ion-battery-with-lcd-capacity-meter.html) and [goBILDA® 20V Smart Dock](https://www.gobilda.com/gobilda-smart-dock-for-20v-battery-dewalt-20v-compatible/) to that mix to unleash heavy-duty 20V action!

Each of the two channels can handle 40A continuously, and up to 50A peak. Motor control is facilitated safely thanks to temperature, current, and reverse-voltage protections. Status LEDS keep you in the know about the signals received by the motor controller, as well as any current, voltage, or temperature errors. A signal arm zone prevents unintentional motion.

The slim footprint allows you to nestle it down inside of your project. The aluminum heatsink doubles as a mounting base, boasting M4 threaded holes on the goBILDA® 8mm grid pattern that allow you to easily fasten it to other goBILDA® components.

# Power Input

Supply anywhere from 9-30V to the XT90 connector to power your motors. Though you can send that power from any suitable battery, the [goBILDA® 20V Smart Dock](https://www.gobilda.com/gobilda-smart-dock-for-20v-battery-dewalt-20v-compatible/) has an XT90 output for heavy-duty powering!

# Signal Input

Plug an RC receiver, Arduino, or any source of a PWM servo-signal into the Channel A and/or Channel B ports. The beefy BEC will supply 6.2V and up to 6A to the servo controller via the + pins so that you can drive servos and other devices without the need for a separate battery.

# Output

Each channel of the motor controller can handle up to 40A of continuous current. You can plug in as many motors as you’d like to each of the two channels—just as long as you do not surpass the current limit of that channel. The bullet connectors allow you to wire-up your motor or build a harness to supply power to multiple motors.

### Need bullet connectors?

This motor controller does NOT include 3.5mm bullet connectors. If your motors do not have 3.5mm bullet connectors, you can [pick up an adaptor](https://www.gobilda.com/connector-style-3-5mm-bullet/) or solder [3.5mm bullet leads](https://core-electronics.com.au/35mm-bullet-lead-mh-fc-300mm-length.html) to your motors to make them compatible with this motor controller.
