5 Hardware Setup Guide
5.1 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.

5.2 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 I2C 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:
http://www.ftdichip.com/VM800B.htm.
More information about MPSSE cables may be found at:
http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_C232HM_MPSSE_CABLE.pdf.
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.
