The Wooden Camera D-Box for URSA Mini/Mini Pro/12K (V-Mount) adds power distribution, standardised remote start/stop and hot swap to the Blackmagic URSA Mini Pro and 12K, and to the EF, PL and B4 mount URSA Mini cameras. It isn't compatible with the Blackmagic URSA Cine 12K or 17K.

It attaches directly to the back of the camera through a special Molex connector, with no external cabling, and controls run/stop through the camera's rear LANC port. Two 3-pin Fischer ports give 24V regulated (2A continuous, 3A surge, shared) and start/stop with any ARRI standard trigger. Two 2-pin connectors with ARRI standard wiring and a D-Tap give 12V unregulated, and USB gives 5V regulated. The IDX V-Mount plate adds two D-Taps, though one may be blocked by the camera's right-side BNC connectors.

The mini 4-pin XLR DC input comes with a pigtail to full-size 4-pin XLR and takes priority over the battery when both are connected. The power supply that comes with the URSA Mini Pro isn't rated high enough to run the D-Box with accessories or to hot swap.
