4d systems 4dlcd - ft843 4.3 embedded spi display ? 201 4 4d systems page 6 of 10 www.4dsystems.com.au 4dlcd - 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 pcbs fpc connector. this is also fragile and should be treated with care, it should not be sub jected 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 websi te. 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 exi ts 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 a re also possible.
