The FT311D Development Module is intended for use as a hardware platform to enable easy evaluation of
FTDI’s FT311D Android Open Accessory USB Host controller. The FT311D Development Module includes
all the necessary components required by a user to begin developing Android Open Accessory
applications based on the FT311D device. The FT311D Development Module behaves like a bridge
between an Android device and the various I/O available. Selection of various modes is performed using
CONFIG[2:0] pins as shown in the Table 4.2.
3.1 Key Features
Easy to use Android Open Accessory Module translating the USB Device port of the android tablet into
any one of the six selectable interfaces like GPIO, UART, PWM, I
3.2 Functional Block Descriptions

Interface Mode Selection
Interface Mode selection is done using CONFIG[2:0] pins. Refer to chapter 4 for the details.
USB Host
USB Host port at CN1 is used for connecting the Android Open Accessory device. The USB host port does
not support other USB device classes.
Interface Signals
The interface signals at CON1 are based on the mode selected by the Interface Mode Selection.
Programming Port
The Programming Port at J7 is used for re-programming the FT311D device with new ROM file.
(NOTE: This is unlikely to be required as the module is delivered ready to use).
