The Avinox DP100 is the original display which shipped with all M1 Motored bikes.
The DP100-F (Flat) and DPC100 are the two new displays released with the M2 and M2S motors.
The cable connections on all three units are the same.
Both the DP100 and DP100-F displays are the same internally. The difference being the case now enables the display to sit on a flat top tube, whereas the original was designed to sit on a slightly rounded top-tube. The new gen displays also do away with the little re-enforcing mouldings around the exterior to make mounting easier :
Original :
The DPC100 loses 4G connectivity but retains Apple Find My. The USB port also drops to 10w instead of 65w and it loses the ambient light sensor. It does however upgrade bluetooth to 5.3 over the 5.1 used on the other two displays. All the units support 12v/2.0a/24w through the lower expansion port for lights etc.
Not that for the DP100 and DP100F displays there are "Global" and "US" versions presumably with different mobile data configurations.
