Get Best Quote
Approx. Price: Rs 250 / Piece
Product Description

These displays were used in old Nokia 5110/3310 cell phones (before the smart-phone fad turned every cell phone into a TV). It’s a 84×48 pixel monochrome LCD display. These displays are small, only about 1.5″ diagonal, but very readable and come with a white backlight. This display is made of 84×48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well
To drive the display, you will need 3 to 5 digital output pins (depending on whether you want to manually control the chip select and reset lines). Another pin can be used to control (via on/off or PWM) the backlight – the backlight LEDs are wired to a transistor.

The display driver is a PCD8544 chip, and it runs at 3.3V so you’ll need a 3V supply handy (you don’t need that much current though, maybe 10mA tops). Logic levels must be 3V to prevent damage but we include a free level shifter chip so you can easily connect it to 5V logic such as an Arduino.

Specifications of LCD 5110

  • 48 x 84 Dot LCD Display
  • Serial Bus Interface with maximum high speed 4.0 Mbits/S
  • Internal Controller No.PCD8544
  • LED Back-Light Run at Voltage 2.7 -5.0 Volt
  • Low power consumption; it is suitable for battery applications

Supports a variety of serial communication protocols (such as the AVR MCU SPI MCS51 serial mode 0, etc.), the transfer rate of up to 4Mbps, can be written to the display data at full speed, no waiting time.
  • by conductive glue to connect the module with the printed version, without having to connect the cable with a metal hook on the module to module fixed to the printed circuit board, which makes it very easy to install and replace.
  • LCD controller / driver chip has bound to the LCD chip module is very small.

  • PCA9685 16-Channel 12-Bit PWM Servo Driver
Get Best Quote
Approx. Price: Rs 300 / Number

Features

  • Contain an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running!
  • 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good when you want to control white or blue LEDs with 3.4+ forward voltages)
  • Support using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs
  • 3 pin connectors in groups of 4, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
  • 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate


Technical Details

Introduction
PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.
