DJI Can Hub

The DJI NAZA-M system communicates with other DJI products (e.g. H3-2D gimbal, BTU module, iOSD mini and iOSD Mark II) via the CAN-Bus port of the NAZA PMU V2. You can plug new DJI products into any spare CAN-Bus port, since CAN-Bus ports on NAZA-M, CAN HUB, GCU, iOSD mini and iOSD Mark II are the same for the communications. When there are not enough CAN-Bus ports for additional DJI products, then a DJI CAN HUB module is recommended.
