Graphic LCD 84x48 - Nokia 5110 Description: The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended for as a cell phone screen. This one is mounted on an easy to solder PCB. It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is a low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. Note: There may be small blemishes on these screens as they are surplus. Note: Your screen may or may not have a diode on the PCB. Dimensions: 45x45mm Documents:
The Ruggeduino The Ruggeduino is powered from one of three sources: USB port: 5V is provided directly from the USB port. A 500mA PTC (resettable fuse) protects the computer from overcurrent.DC power jack: a 2.1mm center-positive DC power adapter can supply 7V - 24V. This power input is also protected by a 500mA PTC (only on the Ruggeduino!)Vin: this connector pin can either source power to the Ruggeduino (7V-24V) or draw power from the DC power jack. When more than one power source is present, the automatic power switching circuit selects external power (DC power jack or Vin, whichever is higher) when available, otherwise USB power is used. The Ruggeduino can supply power to shields or external circuits in three ways: +5V output: the +5V connector pin is the same voltage seen by the microcontroller. This +5V output can typically source 500mA when the DC power jack voltage (Vext) is 9V or less, and less current as Vext increases due to thermal loading on the 5V regulator.
