RC ESC programming adapter

The KINGARD Castle B-Link Bluetooth Adapter connects Castle Creations electronic speed controllers and BEC 2.0 or BEC Pro units to iOS and Android devices. It lets racers and hobbyists adjust settings and review data logs wirelessly without removing the ESC from the model. The adapter suits anyone who wants field tuning without a laptop or cable.

Waterproof field operation

A sealed housing protects the electronics so the adapter can stay mounted in the vehicle during wet or dusty conditions. Power is drawn directly from the ESC, so no separate battery or charger is required during normal use. The app functions offline after the initial download, avoiding data consumption at remote tracks.

Multi-model flexibility

One adapter can be moved between different models, and the companion app stores separate profiles for each. A free account enables settings to be synced across multiple phones or tablets when an internet connection is available. Builders who need simultaneous live telemetry on several vehicles at once will need an adapter for each ESC.

Questions about this item

How do I connect the B-Link adapter to my Castle Creations ESC for wireless programming?

Plug the adapter into the ESC programming port; it pairs with the Castle Link app on iOS or Android without needing a data connection once the app is installed.

What part of the B-Link adapter is most likely to need replacement after extended field use?

The waterproof housing protects the electronics, but the connector pins can wear from repeated insertion; inspect them if pairing becomes unreliable.

What limits how long I can log data continuously with the B-Link adapter?

The ESC onboard memory fills first; the adapter streams logs to the app until that storage is full, then older entries are overwritten.
