A built-in seesaw microcontroller handles button press detection and LED PWM control, so you don't need to dedicate GPIO pins or set up PWM outputs — just plug in via STEMMA QT / Qwiic and go.\n\nEach of the eight JST XH sockets connects to an arcade button's switch and LED via quick-connect cables. An onboard boost converter ensures LEDs light up brightly at 5V even when your microcontroller runs at 3.3V. Chain multiple boards via I2C — with four address jumpers, up to 16 boards (64 buttons) can share a single bus.\n\nKey Features\n\n\n4× Arcade Button Connections – 8× JST XH sockets for switch and LED quick-connect cables\n\nSeesaw I2C Interface – Onboard microcontroller handles button reads and LED PWM over I2C\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support\n\nOnboard 5V Boost Converter – Drives LED illuminators brightly even from 3.3V systems\n\nUp to 16 Boards Per Bus – Four I2C address jumpers for massive button arrays (up to 64 buttons)\n\nBreadboard Compatible – Two rows of 0.1\" breakout pads on each side\n\n3.3V & 5V Logic Compatible – Works with any I2C microcontroller\n\n\nIdeal For\n\nCustom arcade control panels and fight sticks\nInteractive button walls and museum exhibits\nGame controllers and quiz buzzers\nLED-illuminated control interfaces\n\n\nPackage Contents\n\n1× Adafruit LED Arcade Button 1×4 QT I2C Breakout (assembled and programmed)\n\n\n\nImportant: LED arcade buttons, JST XH quick-connect cables, and microcontroller are not included. This is the controller board only.\n\n\nResources\n\nAdafruit LED Arcade Button QT Guide\nArduino Seesaw Library (GitHub)\nCircuitPython Seesaw Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":3032,"title":"Default Title","sku":"AF-5296","price":20.65,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
