1.8 Inch TFT LCD Module 128 x 160 with 4 IO

This lovely little display breakout is the best way to add a small, colourful and bright display to any project.

Since the 1.8 Inch TFT LCD Module display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

The 1.8″ display has 128×160 colour pixels. Unlike the low cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor colour and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 18-bit colour (262,144 shades!).

And the LCD will always come with the same driver chip so there are no worries that your code will not work from one to the other.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic.

We also had a little space so we placed a microSD card holder so you can easily load full-colour bitmaps from a FAT16/FAT32 formatted microSD card.

MAX7219 LED Dot Matrix 4 In 1 Display with 5P Line Module

This is Dot Led Matrix Module incorporating MAX7219 Driver chip. By using this dot LED module in your upcoming project,  you will be able to add some great cool animation.

The individual module features 8×8 LED’s, each controlled very precisely by the MAX7219 driver to generate the colour pattern you wish. The great advantage of using this is users will have control over all of the 64 LED by just connecting 3 output communication wires to microcontrollers like Arduino etc.

This product has 4 Dot Matrix LED’s cascaded to form a single LED Display to allot more area to the user on the display.

Connecting the two modules is also very easy. Only connect the output pins of the previous breakout board to the input pins of the new module, thus with such arrangement, you can connect as many DOT LED Modules to the Arduino as you wish!!! Great……

The MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces micro-controllers to LED matrices. All common micro-controllers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Only one external register is used to set the segment current of each LED.

Requires only three IO ports can drive a dot! No flashing dot matrix display! Support cascade!

1.3 Inch 128×64 OLED Display Screen Module with SPI Serial Interface – V2

OLED’s are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCD’s and LED‘s.

The most attractive thing about using the OLED displays is that they do not need a back-light like conventional LCD/LED screens. The organic material itself has a property known as Electroluminescence (EL), which causes the material to “glow” when stimulated by a current or an electric field. Best energy saving displays ever!!!

This 1.3 Inch 128×64 OLED Display Screen Module offers 128×64 pixel resolution. They are featuring much less thickness than LCD displays with good brightness and also produce better and true colors. 

This OLED Display Module is very compact and will add a great ever user interface experience to your Arduino project. The connection of this display with Arduino is made through SPI interface.

The 1.3 Inch 128×64 OLED Display Screen Module produces blue text on black background with very good contrast when supplied with DC 2.8V supply. The OLED Display Modules also offers a very wide viewing angle of about greater than 160°.

ADS1115 16-Bit ADC- 4 Channel with Programmable Gain AmplifierADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier is mostly used for microcontrollers project which needs an analog-to-digital converter or when you want a higher-precision ADC. ADS1115 16-Bit ADC- provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-end input channels or two differential channels.Additionally, ADC also includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and it’s super easy to use. It is a great general-purpose 16-bit converter.The ADS1115 chip is fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115’s connect on a single 2-wire I2C bus for 16 single end inputs.To get you start, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port and run the example code to start reading data.Pin Description: Features : WIDE SUPPLY RANGE: 2.0V to 5.5VPROGRAMMABLE DATA RATE: 8SPS to 860SPSIt has an Internal low-drift voltage referenceInternal Oscillator.Internal PGA.I2C INTERFACE : Pin-Selectable Addresses.Four single ends Or Two differential inputs.Programmable Comparator.This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpersLOW CURRENT CONSUMPTION: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-DownPackage Includes :1 x ADS1115 16-Bit ADC – 4 Channel with Programmable Gain AmplifierOperating Voltage (V)2 to 5.5Model No.:ADS1115PCB Size ( L x W ) mm28 x 16Weight (g):2Shipping Weight0.005 kgShipping Dimensions9 × 8 × 5 cm
