Link No.
Setting
Status Description
JP1
Opened
Non-
Defaul
t
Self-Powered mode. This setting removes the connection between VBUS
and VCC5V. For self-pow ered operation 5V pow er is received from CN2-1.
JP1
Closed
Defaul
t
Bus-Powered mode. This setting creates a connection between VBUS and
VCC5V. For bus-powered operations 5V power will be output on CN2-1
w hen the module is connected to an upstream USB port.
Table 5.1 – Jumper JP1 Modes
Warning: There should never be more than one power output supplying power to the same net at any
one time. Closing JP1 will cause a direct short between two different power supplies, when a self-powered
set-up is applied and the USB bus is connected resulting in the potential for damage to the module and
other connected circuitry.
5.2 Programming Firmware to the Flash ROM
The FT51A can be programmed using the FTPD-1. CN3 is a dedicated port that can interface with the
FTPD-1.
A list of available examples (at time of writing) is shown below and source code can be found in
