The AUAV Active I²C Hub is an "Active" I²C splitter + booster. The individually selectable voltage level DIP switch on each I²C port allows you to mix 3.3V and 5V I²C logic devices. This module also allows you to "split" the I²C signal coming from the Autopilot GPS+I²C standard connector and a secondary 6-Pin JST-GH connector to plug your GPS module in a pass-through fashion. Additionally, the Hub works as a repeater, which enables you to run longer cables or improve your signal in noisy environments.
2 x 6-Pin JST-GH pass-through for GPS connector.
4 x I²C port peripherals; each has a switch that allows you to set the correct logic level (3.3V or 5V). Sweet!
Yes, this fixes the logic level problem on Digital Airspeed sensors sold by 3DR and HK.
