40x2 lcd module free sample

If you need to display a lot of information on your device, this extra wide LCD will do the job with an active area of 5.8-inches (147.50 millimeters). The 5x8 character matrix on this transmissive STN 40 x 2 LCD screen is good for typical office lighting and is easy to read in dark locations. One of our customers bought a display in the CFAH4002A series to use in an environmental control system for irrigation management.

If you need to display a lot of information on your device, this extra wide LCD will do the job with an active area of 5.8-inches (147.50 millimeters). Like all transflective displays, the 5x8 character matrix on this 40 x 2 LCD screen can be read in direct sunlight, is good for typical office lighting, and is easy to read in dark locations. One of our customers bought a display in the CFAH4002A series to use in an environmental control system for irrigation management.

Our goal is to keep every product available as long as possible. We"ve sold the CFAH4002A series since 2008 and it is still going strong. With a white LED backlight, this FSTN (Film compensated Super-Twisted Neumatic) display module has a higher contrast ratio than the standard STN, resulting in superior sharpness and contrast. A simple current limiting resistor in line with the voltage source works well in most applications. The white LEDs do not demand a current source, although one may be used. For details, see the backlight section starting on page 22 of the datasheet.

NMLCD-M402C-1is 40x2 lcd display character module, arduino, pinout, S6A0069, S6A2067or equivalent controller, wide temperature, yellow green led backlight, STN LCD.

Answer: For the segment type LCD module, if you need to modify the outline size or display content, we will start the drawing paper for your checking.

RC1602B 16x2 Character LCD display has the same specs as RC1602B1. These 2 LCD display modules have the same module dimension 80.0 x 36.0 mm, sharing the same IC ST7066. Default interface is 6800; if you require interface such as SPI or I2C, they’re also available, but the IC will be replaced with RW1063.

Default power supply is 5V (3V is optional). Negative voltage is an available option for 3V module. The difference between RC1602B and RC1602B1 is the position of pins. Pins of RC1602B is at the top; Pins of RC1602B1 is at the bottom. LED can be driven by PIN1, PIN2, PIN15, PIN16 or A and K.

RC1602B LCD Display Module 16 Character x 2 Lines with LED backlight provides various color combinations for backlight, for example, yellow-green, blue, white, amber, red. This LCD module without backlight is also available.

In this tutorial I am going to explain about the pin out, working and control systems of character lcd’s. Character lcd’s comes in many sizes for example 8×1, 8×2, 8×4, 16×1, 16×2, 20×1, 20×2, 20×4, 24×1, 24×2, 24×4, 32×1, 32×2, 40×1, 40×2 and 40×4. In these MxN dimensions, M represents number of coulombs & N represents number of rows.

All these Lcd’s available in market have 14 or 16 pins depending on the vendor/supplier. Also they all contains a same lcd controller in them which controls all their activities. Talks to external peripherals(like microcontrollers) receives data from external devices and displays them on lcd display screen. Generally every character lcd has HD44780 controller in it which controls every operation of character lcd. Some variants and competitors of HD44780 also placed step in embedded market but they are not popular for exampleAIP31066 , KS0066 , SPLC780 and ST7066 lcd controller.

In these 14 pins, 8 are data pins(FromDB-0toDB-7). Three are lcd control pinsRS(Register Select),R/W(Read-Write) &En(Enable). Two are lcd power pinsVcc(+5v)Vss(Gnd). The last pin islcd contrast pin(V0).

If lcd contains 16 pins than the extra 2 pins are LED+ and LED- pins. LED+ and LED- are for lcd’s back light, if you want to switch on the back light of lcd then use these pins other wise leave them void.

Character lcd’s which have pins arranged in two lines like headers, their pin-out is given below. Female header pin-out is shown below. Vendors for ease pre-solder the lcd pins and provide a female header for connections.

Mostly character lcds contains HD44780U lcd controller in them. HD44780 was developed by Hitachi. A single HD44780 can handle up to 80 characters. In 40×4 lcd display total characters which we can display on lcd are 40×4=160. So to control 160 characters we need two HD44780 controllers. To work with two HD44780 controllers we need an extra pin to energize the second controller.

Lcd contrast pin is same like fine tuning your television. In televisions we fine tune stations using remote but in character lcd’s we have to manually do it by varying the resistance. Varying the resistance means we control the input current to lcd. Varying resistance will fade or brighten the characters or data appearing on lcd screen.

Character Lcd’s can be interfaced in 8-bit and 4-bit mode with external controllers. In 8-bit mode all the data lines(DB0-DB7) of lcd are utilized. In 4-bit mode only four data pins of lcd are utilized (DB7-DB4). In 4-bit mode first the 8-bit ASCII value is divided in to two nibbles, first the upper nibble is send on data line and then the lower nibble. 4-bit mode is used when we want to save GPIO pins of our external device like microcontoller. An example of lcd connection with remote controller is shown in the picture below.

I prepared a good tutorial on interfacing character lcd in 8-bit and 4-bit mode with microcontrollers. Demo codes are also presented and explained in the post. Click the below button to take the tutorial.
