1.2 Appearance of Expansion Unit/Module
There are three types of cases for expansion units/modules. One type uses the same case as main unit that of the 90mm,
130mm, and 175mm, while the other two have thinner 40mm and 60mm cases, which are for expansion modules. All
expansion cables (left) of expansion units/modules are flat ribbon cables (6cm long), which were soldered directly on the PCB,
and the expansion header (right) is a 14Pin Header, with this to connect the right adjacent expansion units/modules. In the
following, each of the three types of expansion units/modules is described as an example:
z Expansion unit/module with 90mm, 130mm, or 175mm width case: [-24EA(P), -40EA(P), -60EA(P), -TC16,
