| "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)"

The SparkFun logic level converter is a small device that safely steps down either 5V signals to 3.3V or steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. 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. High voltage (5V for example) to the ""HV"" pin, low voltage (2.8V for example) to ""LV"", and ground from the system to the ""GND"" pin.This revision of the Logic Level Converter fixes the issue with the board not stepping down from 5V to 3.3V correctly.GeneralModelN/AQuantity1 setMaterialFR4 + PCBSpecificationEnglish Manual / SpecYesDownload Link https://learn.sparkfun.com/tutorials/using-the-logic-level-converter?_ga=1.253089033.1490527417.1425711667Packing List1 x Converter 2 x Pin headersPackage Weight:0.006kg (0.013lb)Package Size:1.5cm x 1.3cm x 0.2cm (0.39in x 0.39in x 0.00in)"

It has built-in overcurrent detection, undervoltage detection, overtemperature detection, stall detection, a 5-bit ADC, and a switch input that can be used for either user jog control or as a hard stop function. As if that weren't enough, it also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting.Unlike most stepper motor drivers, the dSPIN is controlled over an SPI link. It has an on-board 16MHz oscillator which allows it to autonomously execute movement commands. That means no more counting steps in your code! It also supports customized acceleration and deceleration profiles to prevent jerky starts and stops. On-board registers track current speed and location. This L6470 Stepper Driver Breakout makes it easy to put the dSpin to work in your project. Simply connect your motors and your SPI-capable microcontroller and get steppin'!

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.

| "INA219 DIY DC Current Sensor Breakout Module - Blue" |
| "This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision.Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter - it can handle high side current measuring, up to +26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels.A precision amplifier measures the voltage across the 0.1ohm, 1% sense resistor. Since the amplifier maximum input difference is +/-320mV this means it can measure up to +/-3.2 Amps. With the internal 12 bit ADC, the resolution at +/-3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is +/-400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1ohm current sense resistor and replace it with their own to change the range (say a 0.01ohm to measure up 32Amps with a resolution of 8mA).

| "Voltage: DC 4~7V; Communication interface: single line; LED drive chip ws2812B integrated LED; RGB wave length: R: 635~700nm, G: 490~560nm, B: 450~490nm; 16 PCS high bright smart LED NeoPixels arranged in round 68mm PCB; Those annulus RGB light can be simple connect one input pin to another (DI-->DO) through output pin cascade; Though cascade, just use one pin of singlechip, you can control LED light as many as possible; Each LED integrated by one piece drive chip become smart and addressable; Each LED has 18mAh constant current drive, so the color will be same. Even though voltage changing is the same, no external resistance needed, the current-limiting resistance make RGB integrated design become slim. Use 5V power supply (working current 4~7V) drive RGB lamp ring.GeneralBrandDuinoPEAKModelN/AQuantity1 setForm ColorBlackMaterialFR4, PCB, LEDSpecificationChipsetWS2812 5050 RGB LEDHardware PlatformArduinoEnglish Manual / SpecNoDownload Link http://duinopeak.com/wiki/index.php?title=RGB_ringPacking List1 x RGB ringPackage Weight:0.012kg (0.026lb)Package Size:6.8cm x 6.8cm x 0.3cm (2.36in x 2.36in x 0.00in)"

| "ESP-12E Wi-Fi Module + ESP8266 Transceiver Module for Arduino" |
| "ESP-12E is an enhanced version ESP8266-12, improve the external circuit, enhanced impedance signal output is better, whether it is stable or anti-jamming capability, have been greatly improved! Before selecting a user for ESP-12's, it does not matter even if the product has been made, enhanced version is fully compatible with previous firmware pin has added the ESP-12 on the basis of six IO ports, SPI mouth leads, develop more convenient, application more extensive. It can be used for remote monitoring of home appliances, bedroom temperature and humidity, and controlling home appliances by the mobile phone. Features: - Compatible with ESP-12; - Communication interface voltage: 3.3V; - IO Port Package: Both SMD and Inline package are available, and the pin pitch is 2.0mm; - Antenna Type: Built-in PCB antenna is available ; - Wireless Network Mode: station / softAP / SoftAP + station; - Wireless criteria: 802.11 b / g / n; - Wi-Fi @ 2.4GHz, support for WPA / WPA2 security mode; - It is very easy to develop projects with AT command. About the Adapter Board:Used to convert the IO ports of ESP-12 to 2.54mm pitch pin headers, so it is easy for beginner to test ESP-12.Before use, the user should first follow these steps:Firstly, Solder the ESP-12 to the adapter board;Secondly, Solder the 3.3V regulator to the bottom of the adapter board;Thirdly, Solder the 1X8P pin header to the adapter board;Because there is a 3.3V regulator onboard, the range of VCC pin on the adapter board can be 3.3V to 5V.Applications: Home automation, sensor networks, industrial wireless control.GeneralModelN/AQuantity1 setMaterialPCB + alloy + plasticSpecificationFrequency2.4GHzWorking Voltage 3.3VEnglish Manual / SpecYesDownload Link http://pan.baidu.com/s/1o6OFQ5cPacking List1 x ESP-12E serial Wi-Fi module1 x Adapter board2 x 8-Pin headers1 x XC6206P332PR sot89 chipPackage Weight:0.012kg (0.026lb)Package Size:6cm x 3.5cm x 2.5cm (2.36in x 1.18in x 0.79in)"
