The CJMCU bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side. The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using.

| "Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 1.5"" (37mm) outer diameter. The rings are ""chainable"" - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has 18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the Netduino or Basic Stamp. Our wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please Google around. An 8MHz or faster processor is required.Comes as a single ring with 12 individually addressable RGB LEDs assembled and tested.GeneralModelN/AQuantity1 setForm ColorBlackMaterialFR4 + PCB + LEDSpecificationEnglish Manual / SpecNoDownload Link More information, pls refer to: http://www.adafruit.com/products/1643Packing List1 x LED development boardPackage Weight:0.011kg (0.024lb)Package Size:3.8cm x 3.8cm x 0.3cm (1.18in x 1.18in x 0.00in)"

| "Geeetech 1.8-Degree Nema 14, 35 BYGHW Stepper Motor for 3D Printer" |
| "The powerful stepper motors are mainly used for holding or positioning applications, as for example plotters, printers, moving lights or mirror mounts etc. A stepper motor (or step motor) divides a full rotation into a number of discrete steps.The motor's position can then be commanded to move and hold at one of these steps. Once stopped, the stepper holds the load steady with a holding torque.This is a NEMA 14 stepper motor. The NEMA 14 is smaller and generally lighter than for example a NEMA 17, however, its size is not an indication of its power. Features: 1. Inexpensive, as the rotor contains no winding slip rings or commutator.2. Easy to position moves in steps based on pulses supplied to the stator windings.3. Direction of rotation is changed by reversing the pulse sequence.4. Speed control through frequency of pulses or pulse rate Applications: Computer-controlled stepper motors are mainly used for holding or positioning applications, as for example plotters, printers, moving lights or mirror mounts.
