The Adafruit Adafruit Wii Nunchuck Breakout Adapter fits snugly into the Wii connector, and performs the level shifting and power regulation needed to use the controller with any microcontroller or microcomputer.\u003c\/p\u003e\u003cp\u003eThe Wii controllers use a standard I2C interface, and there's existing code for both Arduino and CircuitPython\/Python for quick integration with an Arduino UNO, Feather, or even a Raspberry Pi. We like to use these with the Wii Nunchuck, as you can get an X-Y joystick, two buttons and an accelerometer all in one hand-held package. All data is transmitted over I2C address 0x53, and the address can not be changed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWe use extra thicc 2.0mm PCBs for this breakout, and made cut-outs for the grabber-notches, so that the controller connection is snug, and won't rattle or come loose!\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTo make using it as easy as possible, we’ve created this breakout in Stemma QT form factor.

You \u003cem\u003ecould\u003c\/em\u003e upgrade to a board with massive number of GPIO like the Grand Central, or you could pop on one of these boards. Connect it over I2C and then you can send\/receive I2C commands to control the GPIO pins to write and read them. It's going to be slower than direct GPIO access, but maybe that doesn't matter if it takes a millisecond instead of a microsecond. You only need the two I2C pins, and you can even share the I2C port with other sensors and devices. Heck, you can even add more expanders for massive I\/O control!\u003c\/p\u003e\u003cp\u003eThe AW9523 is a twist on the common I2C expander:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFirst up, its very affordable - who doesn't love that?\u003c\/li\u003e\n\u003cli\u003eIt has 16 I\/O pins, that'll double most boards' pin count\u003c\/li\u003e\n\u003cli\u003eFour I2C address options, so you can connect 4 expanders to one bus\u003c\/li\u003e\n\u003cli\u003eEach pin can be an input or an output\u003c\/li\u003e\n\u003cli\u003eIRQ output can alert you when input pins change value\u003c\/li\u003e\n\u003cli\u003eThis chip \u003cem\u003edoes not\u003c\/em\u003e support internal pull-ups or pull-downs, you will need to add an external resistor if you need one\u003c\/li\u003e\n\u003cli\u003eHowever, it \u003cem\u003edoes\u003c\/em\u003e have 8-bit linear constant-current LED dimming support so you can connect LEDs without resistors and have great looking dimming without PWM\u003c\/li\u003e\n\u003cli\u003eThe first 8 pins can be configured as open drain (as a group)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe lack of internally-configurable pull's is a bit of a bummer, but we think the expander more than makes up for it with the constant-current LED drive. If you're using an expander to add lots of controllable LEDs, this board will make it very easy. Since its constant-current, you \u003cem\u003edon't\u003c\/em\u003e need resistors in line with each LED (although it won't hurt if you do): simply connect the LED anode to one of the many VIN pads, then connect the cathode to the GPIO pin.\u003c\/p\u003e\u003cp\u003eOf course, you can control any buttons or other I\/O with the pins - we just think this board is particularly suited to LED driving. There's also an interrupt output, you can enable the pin-change IRQ for any pins so you can be notified when its time to read the I\/O states.\u003c\/p\u003e\u003cp\u003eOne oddity about this chip is the default I2C address determines the initial boot-state of the pins. Our libraries immediately soft-reset and configure all the pins to inputs and push-pull so you can expect the same behavior no matter what the I2C address is. However, we recommend you check the datasheet Table 1 to make sure this doesn't affect your hardware.\u003c\/p\u003e\u003cp\u003eWe've written both Arduino and CircuitPython\/Python libraries for the AW9523, so you can get started whether you have an Arduino-compatible UNO or a Raspberry Pi 4 - or anything in between.\u003c\/p\u003e\u003cp\u003eTo get you going fast, we spun up a custom made PCB in the \u003cstrong\u003eSTEMMA QT\u003c\/strong\u003e form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the AW9523 or to chain it with a wide range of other sensors and accessories using a \u003cstrong\u003ecompatible cable\u003c\/strong\u003e. \u003cstrong\u003eQT Cable is not included\u003c\/strong\u003e, but we have a variety in the shop. \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003e\u003cstrong\u003eAW9523 Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e16 multi-function I\/O, each for LED drive (current-source dimming) or GPIO mode\u003c\/li\u003e\n\u003cli\u003e256 steps linear dimming in LED drive mode\u003c\/li\u003e\n\u003cli\u003eAny GPIO can be configured as an input or an output independently\u003c\/li\u003e\n\u003cli\u003eSupport interrupt, 8us deglitch, low-level active\u003c\/li\u003e\n\u003cli\u003eStandard I2C interface, AD1\/AD0 select I2C device address\u003c\/li\u003e\n\u003cli\u003eSDA, SCL, SHDN, and all GPIO can accept in 1.8V logic input\u003c\/li\u003e\n\u003cli\u003eESD protection: ±4000V HBM (MIL-STD-883H Method 3015.8 standard）\u003c\/li\u003e\n\u003cli\u003eLatch-up ：±450mA（ JEDEC STANDARD NO.78C SEPTEMBER 2010 standard）\u003c\/li\u003e\n\u003cli\u003eSupply shutdown function, low-level active\u003c\/li\u003e\n\u003cli\u003e2.5V~5.5V power supply\u003c\/li\u003e\n\u003cli\u003eI2C address default 0x58 (can be 0x59, 0x5A or 0x5B)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 38.0mm x 17.8mm x 4.5mm \/ 1.5\" x 0.7\" x 0.2\" \u003c\/p\u003e\n\u003cp\u003eProduct Weight: 2.5g \/ 0.1oz \u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003cli\u003e\nAW9523 English Datasheet \u003c\/li\u003e\n\u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493263212621,"sku":"uya1787258281701","price":3.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/adafruit-aw9523-gpio-expander-and-led-driver-breakout-stemma-qt-qwiic_1.jpg?v=1787258286"}],"url":"https:\/\/www.grandorchard.shop\/collections\/breakout.oembed","provider":"My Store","version":"1.0","type":"link"}
