It's built around an onboard \u003cstrong\u003eATtiny404\u003c\/strong\u003e microcontroller that reads the button and drives the LED and buzzer, so your main microcontroller talks to all three over a single \u003cstrong\u003eI2C\u003c\/strong\u003e connection instead of wiring up three separate components. A Soldered Arduino library is available for reading the button and controlling the LED and buzzer.\u003c\/p\u003e\n\u003cp\u003eThe board communicates over I2C at a default address of \u003cstrong\u003e0x30\u003c\/strong\u003e and is \u003cstrong\u003eQwiic\u003c\/strong\u003e compatible, so it connects to any Qwiic-enabled microcontroller without soldering. Beyond the Qwiic connector, it also breaks out VCC, GND, SCL, and SDA on a standard header, plus a UPDI pin for reprogramming the onboard ATtiny404 if you ever need to change its firmware.\u003c\/p\u003e\n\u003cp\u003eBecause the button, LED, and buzzer are all handled by the onboard microcontroller, this board is useful anywhere a project needs simple user interaction without extra wiring: a confirm button with an audible beep, a status LED paired with an alert tone, or a menu selector. It's also a great starting point for beginners learning I2C and digital I\/O for the first time, since there's no breadboard wiring involved, just a single Qwiic cable.\u003c\/p\u003e\n\u003cp\u003eThe board runs on \u003cstrong\u003e3.3V or 5V\u003c\/strong\u003e and measures \u003cstrong\u003e22 x 38 mm\u003c\/strong\u003e, with two mounting holes sized for M3 screws.\u003c\/p\u003e","brand":"Soldered Electronics","offers":[{"title":"Default Title","offer_id":65125291360605,"sku":"333182","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/5029\/1549\/files\/pinout.png?v=1783342838","url":"https:\/\/soldered.com\/products\/button-led-buzzer-board-with-qwiic","provider":"Soldered Electronics","version":"1.0","type":"link"}
