The MGL iEFIS Explorer Lite is a classic G4 Lite iEFIS with an 8.5" touch display. Based on the G3 architecture, it has limited built-in connectivity but can be expanded with the use of the iEFIS Extender.
Built-in interfaces include:
Pitot-static
2x RS-232
CAN bus
Audio
With an added iEFIS Extender:
AoA
8 analog / digital inputs
5 digital outputs
OAT sensor input
5 RS-232 (6 total usable with classic Lite)
iEFIS Lite contains an internal AHRS, but an external SP-7 or SP-9 AHRS is highly recommended for best results. An SP-6 or SP-9 is required for magnetic heading.
