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

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.
