Portkeys 15.7" 5-Pin BM5 to Micro-USB Cable for Tilta Nucleus-Nano

Connection for BM5 and Nucleus-Nano

This 15.7-inch cable links a Portkeys BM5 monitor with a 5-pin connector to the micro-USB port on a Tilta Nucleus-Nano focus motor. It enables direct focus control from the monitor during shoots. The fixed length suits rig-mounted setups where both devices sit close together. A dedicated cable avoids adapter clutter on set.

For BM5 owners driving Nucleus-Nano

Videographers using a BM5 monitor and Nucleus-Nano motor gain native control without extra boxes. Operators needing longer runs between monitor and motor should look at other options. Users with monitors lacking a 5-pin BM5 output cannot use this cable. Builds requiring wireless focus or different motor protocols need separate solutions.

Behaviour on extended takes

The short 15.7-inch run keeps signal paths tight for consistent motor response during long takes. Fixed wiring avoids intermittent contact that can appear with loose adapters over time. Durable construction withstands repeated coiling and uncoiling on daily shoots. No active electronics in the cable means no heat buildup during continuous operation.
