CVM01 Expansion Module
CVM01 (469535.004) is an expansion module, which allows to connect TFT/STN panels via 40-pin
2.54 mm pitch J5 connector or additional RGB monitor with standard VGA interface via P1 D-Sub
connector. CVM01 has a DAC which converts digital input into analog VGA signal. This expansion
module is connected to CPB902 J16 header with 40-thread cable. The following figure presents
location of CVM01 connectors and other components.

The CVM01 P1 VGA connector has the same pin assignments as CPB902 P7 connector (see
in subsection 4.3.7.1). The pinout of CVM01 J5 connector is given in the table below.
CVM01 provides possibility to adjust the display driver power voltage (VEEP) with R5
potentiometer, and to set the digital interface power voltage with J2-J4 jumpers. Closing J3 and J4
sets VDDP = +3.3 V, closing J2 and J3 sets VDDP = +5 V.
