Table 5.2 – Solder Links JP2 Pin Description
Note: There should never be more than one power output supplied to the same net. Failure to properly
remove solder from JP1 and JP2 can 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 damage to the UMFT201XA
module and the target circuit.
5.2
The UMFT201XA has two solder links fixed to the top side of the PCB. These solder link can be adjusted
by removing the solder linking the two PADs to produce an open or by placing a solder bridge to produce
a short.
By default the UMFT201XA has both solder links shorting their pads. To allow for enhanced flexibility of
this module remove both solder links and wire the header pins according to the power setup required.

Description
Connects internal 3.3V regulator to VCCIO. This restricts signal drive to only 3.3V
level signals.
Disconnects internal 3.3V regulator connection to VCCIO. This mode allows for the
supply of 1.8V-3.3V power from an external power supply, thus allows the
processing of signals with logic levels between 1.8V and 3.3V. VCCIO can be
adjusted to match the interface requirements of external circuitry.
Description
Connects VBUS to VCC. This mode is known as “USB-Powered” mode.
Disconnects VBUS to VCC. This allows the supply of power from an external power
supply. This mode is known as “Self-Powered” mode.
