Nokia 5110 LCD Module Blue Back light
Operation of Nokia 5110 LCD Display Module at 3.3V :
Many devices that can be used with an Arduino, require a power supply of 3.3V. This is also the case with the Nokia 5110. The best way to deal with 3.3V devices is to take an Arduino Pro, which can run on 3.3V.
Operation of Nokia 5110 LCD Display Module at 5V :
Because VDD max = 7V, the PCD8544 controller can handle 5V, but the Nokia 5110 LCD works best at 3.3V. The four resistors of 10kΩ avoid streaks on the LCD display.
Power supply voltage: 2.7V-3.3V,5V is OK, but part of the screen becomes black when tested.
Data interface level: 2.7-5V.
Backlight power supply voltage: highest 3.3V.
Dimensions : 43.6 x 43.1 (LxW) mm.
Installation diameter: 2 mm.
Pin Configuration :
1. RST- reset
2. CE- chip selection
3. DC- data/commands choice
4. DIN- serial data line
5. CLK- serial Clock Speed.
6. VCC- 3.3V
7. LIGHT- backlight control terminal
8. GND- power negative
