Each XH pair lets you connect one arcade button that has a built in LED illuminator, and makes it easy to use with a breadboard\/perfboard or with a STEMMA QT (Qwiic) connector for instant I2C connectivity on any platform.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note, each order comes with one assembled and programmed PCB but no LED arcade buttons or JST XH quick connect cables.\u003c\/strong\u003e \u003ca href=\"\/en-eu\/?q=com04\" target=\"_blank\"\u003eWe have a wide range of colors and sizes\u003c\/a\u003e, so pick your favs to go along, this is just the controller board that plugs into a microcontroller.\u003c\/p\u003e\n\u003cp\u003eA built-in microcontroller is pre-programmed with our seesaw firmware so button presses and LED PWM controlling is done all over I2C. You can even connect multiple board by chaining the I2C and cutting open the I2C address jumpers - with four jumpers you can have up to 16 of these boards on a single I2C bus. Adafruit have \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_Seesaw\" target=\"_blank\"\u003eArduino\u003c\/a\u003e and \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_CircuitPython_seesaw\" target=\"_blank\"\u003eCircuitPython\/Python\u003c\/a\u003e libraries for controlling the Arcade 1x4's so you can use any microcontroller\/computer for quick creation of glowy button interfaces, without setting up PWM outputs. They found that many LEDs in buttons really want 5V power to light up, and are dim or dark at 3.3V, so they added a small boost converter to let you light up at 5V even if the microcontroller you are using is 3V power.\u003c\/p\u003e\n\u003cp\u003eYou can also fit the breakouts onto a breadboard if you like - with two sets of breakout pads, there's plenty of flexibility for any kind of use. There are two rows of 6-pin contacts on a 0.1\" grid on both sides. Solder in both sides for mechanical stability.\u003c\/p\u003e\n\u003cp\u003eSoldering is required to attach the header for breadboard use, if you have \u003ca href=\"\/en-eu\/collections\/stemma-qt\" target=\"_blank\"\u003eSTEMMA QT\/Qwiic connectors\u003c\/a\u003e its a simple plug-in to get working. \u003cstrong\u003eA microcontroller is required to drive this board, it isn't stand-alone.
