-FT843 4.3” Embedded SPI Display

Connection Detail

The 4DLCD-FT843 Display features a 10 way flexible

FPC, which is designed to connect into a 10 way FPC

connector on a PCB.

Please note, the display FPC is fragile and contains

many components, so the main body of the FPC

should not be bent or subjected to excessive forces

or be twisted, else the flex may be damaged and the

display will no longer function correctly.

Out of the main body of the flex, is a thin portion

which contains the 10 signals, which connects to

the target PCB’s FPC connector. This is also fragile

and should be treated with care, it should not be

subjected to excessive bending or twisting else it

may be damaged.

The 4DLCD-FT843 Display is designed to be easily

connected to a target host PCB. 4D Systems offers

two products which may be useful.

One is an Arduino Sheild nicknamed ADAM

(Arduino Display Adaptor Module), which is

designed to connect directly to an Arduino, and

features a 10 way FPC connector to connect the

4DLCD-FT843 Display, along with a micro-SD socket

and associated jumpers.

The other product is a simple breakout board,

which features a 10 way FPC connector, and then a

single 2.54mm pitch row of male pins to plug

directly into a breadboard or into a host PCB.

For detail on these products, please refer to the

respective product pages on the 4D Systems

website.

The 4DLCD-FT843 Display connects to a target Host

Processor / MCU using a 3.3V SPI Bus, and also

features an Interrupt Pin and Shutdown Pin for

applications which can make use of them.

The Display has the ability to generate PWM audio,

both Mono PCM and Polyphonic MIDI, which exits

the display module via the 10 way FPC, and should

then be fed into a simple filter and amplifier circuit.

This circuit is shown in Section 6.0 and should be

treated as the recommended circuit, however

alternative circuits are also possible.
