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.

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.
