ARD-LCD-1.8 1.8 inch Color TFT LCD Display for 3.3v Logic Microcontroller with SD card
US$18.15
An 1.8 inch TFT LCD that is super useful for small project designs and gives a very sharp/nice picture quality which works amazing well with 3.3v logic level microcontrollers. It is possible to interface with 5v Logic Arduino Microcontrollers by using 1k resistor on the Data Lines or a Level Shifter. Unfortunately this display is not a touchscreen display, however it makes it up with the included SD Card Slot, Not Micro which you finally have a reason to use your SD Card adapters or SD Cards. Soldering not required to get the display to work, but requires some soldering for the SD card functionality (4 soldering holes on the other side).

ILQ2 NPN Phototransistor Quad Channel DIP16
US$3.21
The ILQ2 is a silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. The ILQ74 is especially for driving medium-speed logic, where it may be used to eliminate troublesome ground loop and noise problems.

LED-155 4 WS2812 5050 RGB Programmable LED Driver Development Board
US$2.79
This small square shaped LED driver board is based on the WS2812 LEDs that operate at 5VDC and are addressable. Thanks to the small footprint, you can use this board for any applications that has a space constraint. The LEDs are addressable so you can wire a bunch of them provided you are supplying enough current to make a daisy chain. Each board will contain four WS2812 LEDS on board and a small hole in the middle for M3 screw mounting.

ARD-5050 8 5050 SMT RGB LED Array Breakout Board
US$7.69
This module is ideally suited to adding a slightly different light display to your project. This module lets you control 8 ultra-bright RGB LEDs to display your information in a bold and bright way, taking your project to new light levels. The LEDs operate at 5v as they are based on the WS2812. Each LED is individually addressable to provide red, blue, green and any combination of them. Unfortunately a printing error in the silkscreen on the module has led to the GND being labelled as VCC.

LCD-OLED-0.91 0.91 Inches OLED I2C - White Text
US$10.95
This screen is 25cm wide and 10cm tall offering very small real-estate with a hefty cost, it may seem counter intuitive to buy this display until you realise it is based on OLED. The text are always sharp and clear to read on OLEDs compared to the standard pixel based LCDs. This screen has a higher resolution of pixels 128x32, allowing for more complex designs to be shown. This screen will not require backlight! It runs on four wires and connects via the I2C , so you can start addressing the display or multiple display if want to. All you need to get this display running is some jumper wires and Arduino Microcontroller!
