3 Function Description
The FT311 GPIO Board is intended for use as a hardware platform to enable easy evaluation of GPIO and
PWM interfaces in the FT311D Development Module. The FT311 GPIO Board has LEDs and switches to
validate the GPIO and PWM interface of the FT311D device by a user to begin developing Android Open
Accessory applications based on the FT311D device. The FT311 GPIO Board can also be used with the
Vinco Development Module as a LED and keypad interface.
3.1 Key Features
FT311 GPIO Board consists of
8 LEDs. They are LED7, LED6, LED5, LED4, LED3, LED2, LED1 and LED0
8 switches. They are PB7, PB6, PB5, PB4, PB3, PB2, PB1 and PB0
8 jumpers for enabling 3.3V supply for the LEDs. They are JP7, JP6, JP5, JP4, JP3, JP2,
JP1 and JP0
Connector P8 to interface with the FT311D Module
Power supply socket CN1 to connect external 5V DC supply.
Connectors to interface with Vinco Development Module. They are J1, J2, J3, J4, J5 and
J6
Voltage regulator U1 to convert 5V to 3.3V
3.2 Functional Block Descriptions
The following paragraphs describe each function within FT311 GPIO Board. Please refer
to the block diagram shown in Error! Reference source not found.Error! Reference
source not found.Error! Reference source not found..
Power Supply
The FT311 GPIO Board consists of a power supply socket CN1. External power is
plugged into CN1. The 5V power is converted to 3.3V using linear voltage regulator U1.
Jumpers
The Jumpers JP7-JP0 are used to open or close a 3.3V supply to the corresponding
resistors R7-R0.
Resistors
The resistors R7-R0 are the current limiting resistors limiting the current flow to the
corresponding LED.
LEDs
The LED7–LED0 can be controlled from any of the 3 interfaces; Push Button Switch,
FT311D Module Interface Connector and Vinco Interface connectors.
Push Button Switch
The Push Button Switches PB7-PB0 can be used to switch ON the LEDs. When a Push
button switch is pressed the corresponding LED is ON. When Push button switch is not
pressed the LED is OFF. The Push button will send a logic 1 in the default state and
logic 0 in the pressed state to the corresponding interface pins to act as GPIO inputs to
the FT311D device.

FT311D Module Interface Connector
The LEDs can be controlled from the FT311D Module. The LEDs are OFF by default.
When the GPIO pin connected to the FT311D Module is driven LOW the corresponding
LED is ON.
Vinco Interface Connector
The Vinco Interface Connector is used to connect the FT311 GPIO Board to the Vinco
Development Module. The LEDs can be controlled using this interface. By default the
LEDs are OFF. When the GPIO pin connected to the Vinco Development Module is driven
LOW the corresponding LED is ON.
