Bus-Powered mode. This setting creates a connection between VBUS and

VCC5V. For bus-powered operations 5V power will be output on CN2-1

when 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.
