Castle B-Link Bluetooth Adapter

The Castle B-Link Bluetooth Adapter is a wireless accessory for programming Castle Creations electronic speed controllers and BEC 2.0 or BEC Pro units. It connects to Apple iOS and Android devices via Bluetooth so users can adjust settings and view data logs without cables. The adapter carries a 25-year heritage of innovation from the manufacturer.

RC hobbyists who want field programming

This adapter suits RC enthusiasts who need to change ESC parameters or review logs at the flying field or track without disassembling the model. Its waterproof design allows it to remain installed between sessions. Builders who do not use Castle Creations ESCs or the supported BEC units should look at something else because the adapter only communicates with that specific hardware ecosystem.

Verify ESC compatibility and app access

Before ordering, confirm that your speed controller is a current Castle Creations ESC, a compatible older model, or a BEC 2.0 / BEC Pro unit. Ensure you have an Apple iOS or Android device capable of installing the free configuration app from the respective store. Note that initial account creation for cloud sync requires an internet connection, although the app itself works offline once installed.

Questions about this item

Which Castle Creations ESC or BEC model do I need to already own for the B-Link adapter to work?

Will the adapter connect to an older Castle ESC that I have kept from a previous build?

Yes, it supports many older Castle Creations ESC models in addition to current ones, so your existing ESC may be compatible.

How can I confirm the adapter is communicating correctly after I install it in the model?

Open the free Castle app on your iOS or Android device; if it discovers the adapter and lets you program settings or download data logs, the link is working.
