Description。The SparkFun 3.3V FTDI Starter Kit gives you just what you need to get started with FTDI FT232RL USB to serial IC. The pinout of the included board matches the FTDI cable standard to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.。The SparkFun FTDI Basic Breakout was designed to decrease the cost of Arduino development and increase ease of use(the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.。The included cable is a USB 2.0 type B to Mini-B 5-pin black cable.

。Description。This is SparkFun Beefy 3 FTDI Basic Breakout for the FTDI FT231X USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. Built upon the same foundation as our 3.3V SparkFun FTDI Basic Breakout， the Beefy 3 is equipped with an AP2112K voltage regulator making this FTDI basic breakout board capable of handling a current load of up to 600 mA! With the addition of a more "Beefy" voltage regulator your will now be able to power a 3.3V project directly from the FTDI. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.。This board brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector. The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND， green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.。There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working， however this board now requires a Micro-B USB cable. The FTDI Cable is well protected against the elements， but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.。This board was designed to decrease the cost of Arduino development and increase ease of use(the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.

Description。Your 5V system can wield great power with this big， beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!。The heart of the board is sealed， SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor， and an LED tells you when the relay is closed. This is kit， so it comes as through-hole parts with assembly required， which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.。There are some pretty beefy traces connecting the relay to the load pins， but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load， you'll need to solder directly to the board. As always with high current and voltage， play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time， but in an enclosed area heat can build up.。Note：Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity.

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.

Before the wireless joystick， radio-controlled projects used hobby RC transmitters， the same ones used for RC cars， boats and planes. The problem with these transmitters is that many aren't customizable， and the ones that are tend to be too expensive for many of us. The Wireless Joystick Kit offers a custom wireless solution for those who want to control their project their own way.。Equipped with the increasingly popular SAMD21 onboard， all you need is to assemble the SparkFun Wireless Joystick into the configuration you want and add your own XBee and lithium ion battery into the provided sockets. The Wireless Joystick Kit can be assembled into a configuration that utilizes dual joysticks for better RC steering robots(like tanks)or a single joystick configuration with four 12mm momentary pushbuttons(a setup similar to what older game consoles used). We have provided a full Hookup Guide that gives assembly instructions， as well as a tank-steering motor controller tutorial to help get you started!。Please be aware that the SparkFun Wireless Joystick Kit is。NOT supported on Windows 7/8。due to a lack of support drivers for those specific OS's.。Note：This kit will need to be assembled before use， so a beginner's knowledge of soldering will be required. Additionally， in an effort to keep shipping rates down and make this kit available to people throughout the world without delay， there is no XBee or lithium ion battery included.。Get Started with the Wireless Joystick Kit Guide

The Qwiic pHAT connects the I2C bus(GND， 3.3V， SDA， and SCL)on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses， you can stack as many sensors as you'd like to create a tower of sensing power!。The Qwiic pHAT V2.0 has four Qwiic connect ports(two on its side and two vertical)， all on the same I2C bus. We've also made sure to add a simple 5V screw terminal to power boards that may need more than 3.3V and a general-purpose button(with the option to shut down the Pi with a script). Also updated， the mounting holes found on the board are now spaced to accommodate the typical Qwiic board dimension of 1.0"×1.0". This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header as well as the NVIDIA Jetson Nano and Google Coral.。Note。When placing a Raspberry Pi and the pHAT in an enclosure(like the Pi Tin)， we noticed that the pHAT was not fully inserted in Pi's header pins. For a secure connection， you'll need to add a pair of 1x20 stackable headers to extend the pins to your cart.。The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.
