DescriptionThe SparkFun Qwiic LED Stick features ten addressable APA102 LEDs， making it easy to add full color LED control using I2C. Write to individual LEDs to display a count in binary， or write to the whole strip for cool lighting effects. You can even add more LEDs to the end if you need to. We've written an Arduino library and Python package that take care of the I2C and communication to the LEDs so all you have to do is decide what color each LED should be.The LED Stick has a default I2C address of 0x23 but can be changed with a simple command， allowing you to control up to 100 LEDs(10 Qwiic LED Sticks)on a single bus! The address can also be changed to 0x22 by closing the solder jumper on the back of the board.This board is one of our many Qwiic compatible boards! Simply plug and go. No soldering， no figuring out which is SDA or SCL， and no voltage regulation or translation required!Warning：Using a lot of LEDs can draw a lot of current. Make sure to consider the power limits of your setup. If you expect your LED chain to draw more than 600mA of current， connect your external supply directly to VLED. Closing the jumper from VLED to VCC will add a 4.7uF decoupling capacitor.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the Qwiic LED Stick GuideFeatures10x APA102C addressable LEDs driven by an ATTiny85Default I2C Address：0x23(Adjustable to 0x22 via Jumper)2x Qwiic Connectors

DescriptionThe PQ12 series of micro linear actuators are ideal for applications requiring precise positioning and compact size. Weighing in at just 22 grams， the PQ12 is incredibly light as well as compact. The affordably-priced PQ12 is the most powerful actuator of it's size. This is why it has become a popular choice for OEM manufacturers as well as Arduino and RC hobbyists. Some industries where the PQ12 are in use include：prosthetics， robotics， medical， simulation.The PQ12-R series of linear servos operate as a direct replacement for standard rotary servos. They use the same standard 3 wire connector， ground power and control. Regardless of how you drive your servos， be it with an RC receiver， an Arduino board， or a VEX micro-controller， the PQ12-R servo will function in place of a regular servo， but with the added benefit of providing linear motion. The PQ12-R is available in a 20mm stroke coupled with gear ratio options of 30：1， 63：1 and 100：1 cover a large variety of applications.The PQ12-100-6-R has：a 100：1 gear ratio for maximum lifting force； 6VDC operating voltage； and a servo(PWM)interface. This powerful little actuator can lift 50N(～5kg)!The datasheet doesn't mention a minimum operating voltage， but we've tested this actuator at 5VDC and it seems to work just fine. The maximum force and movement speed are reduced of course.FeaturesGearing Option：100：1Peak Power Point：40N @ 6mm/sPeak Efficiency Point：20N @ 8mm/sMax Speed(no load)：10mm/sMax Force(lifted)：50NMax Side Load：10NBack Drive Force：35NStroke：20 mmInput Voltage：6 VDCStall Current：550mA @ 6VMass：22gOperating Temperature -10℃ to +50℃Positional Repeatability：±0.1mmMechanical Backlash：0.25 mmAudible Noise：55dB @ 45cmIngress Protection：IP-54Maximum Duty Cycle：20%PWM(Servo)signal：Fully retracted：2.0ms @ 50HzFully extended：1.0ms @ 50Hz
