After disassembly the LCD's transparent light guide can be trimmed down to the size of the LCD:\\ {{:electronic:lcd:dsc_0299a.jpg?400|Nokia 3310 LCD trimmed front}} {{:electronic:lcd:dsc_0300a.jpg?400|Nokia 3310 LCD trimmed back}} \\ \\ I have some spare Diymore Nokia 3310 adapter PCBs that can be modified to accommodate them:\\ {{:electronic:lcd:pc094071b.jpg?200|Nokia 3310 adapter PCB top}} {{:electronic:lcd:pc094070b.jpg?200|Nokia 3310 adapter PCB bottom}} \\ \\ The four LEDs were removed from the top of the Nokia 3310 adapter PCB, and the capacitor on the bottom was replaced with a wire. The capacitor was relocated to the Vlcd pin where it again acts as an external capacitor for the LCD voltage booster. At this stage I have made no provision for a backlight.\\ |{{:electronic:lcd:p9294745a.jpg?400|Modified Nokia 3310 adapter PCB top}}|{{:electronic:lcd:p9294746b.jpg?400|Modified Nokia 3310 adapter PCB top}}| \\ \\ {{:electronic:lcd:nokia_2280_pcb-b.png?800|Modified Nokia 3310 PCB circuit}} \\ \\ \\ ^ PCB Connector pin-out ^^^ Arduino test rig || ^Pin#^Label^Description^Pin^colour| ^1|Vlcd|Charge pump((1μF to ground on adapter board))|-|-| ^2|Clk|Serial Clock|13|Green| ^3|SDA|Serial Data In|11|Blue| ^4|GND|Power Ground| |Brown| ^5|CS|Chip Select|10|Yellow| ^6|RST|Reset|8|Grey| ^7|nc|(no connection)|-|-| ^8|Vdd|2.7V to 3.3V| |Orange|
