4.3 MC35 / MC35i – interface and connector comparison
MC35 and MC35i are equipped with a 40-pin 0.5mm pitch ZIF connector that connects to the
cellular application platform. The ZIF connector is completely the same for both devices.
The host interface incorporates several sub-interfaces described in the following chapters
MC35 and MC35i are totally PIN compatible. Some of the MC35 signal names were
changed on MC35i but the functionality is completely identical with both modules.
The next table shows a ZIF connector - PIN overview
