Power Configuration
There are 5 methods of powering the VM800C board.
1) USB Power(5V) - Connect USB power through micro-USB cable to CN2
2) DC IN(5V) - Connect 5V to CN1
3) DC IN(3.3V) - Connect 3.3V to CN1 and short J5 pin 7 and 8
4) J5 Power(5V) - Connect 5V to J5 pin 7
5) *J5 Power(3.3V) - Connect 3.3V to J5 pin 7 and 8
*Warning: Applying 5 V accidently in this mode may cause permanent demage to the VM800C module.
The following table summarise how to power the VM800C board using the various methods.

MPSSE Setup
To give a quick start with the VM800C development board, a Windows based Sample Application and
demo applications are provided for users to experiment and experience the FT800 in the VM800C
system. The following paragraphs provide a short description for development procedures.
MPSSE is a “multi purpose synchronous serial engine” interface available in some FTDI device (e.g.
FT2232D, FT232H, FT2232H anf FT4232H). This engine allows users to bridge from a USB port on a PC to
an I
2
C or SPI interface. Sample code is available for driving the FT800 over this interface with a FT232H
device that has been integrated into a cable. This device is available in the VA800A-SPI board, or
C232HM-EDHSL-0(5V) cable or C232HM-DDHSL-0(3.3V) cable.
VA800A-SPI is a MPSSE module accessory which can connect to the VM800C modules directly. Detailed
information of VA800A-SPI can be found at:
More information about MPSSE cables may be found at:
In this section it is assumed the 5V version of the MPSSE cable (FTDI part no C232HM-EDHSL-0) is used.
In case a 3.3V version of the MPSSE cable (FTDI part no C232HM-DDHSL-0) is available, the setup is
similar except for the power pin connection. Refer to table 5-1 for board power configuration.
