MyChron Expansion is the channel multiplier improving MyChron4/MyChron4 2T and MyChron5/MyChron5 2T performances, thanks to four additional channels and a further connector for the CAN bus. Through this last connector MyChron4/MyChron5 can be connected to LCU Lambda controller, GPS, SmartyCam HD or a Data Key for data download. Thanks to its specific wirings, MyChron Expansion powers MyChron4/MyChron5 and its peripherals with an external battery, avoiding internal battery consumption.
