ELECFREAKS Micro:bit Sensor:bit Expansion Board - GVS Interface Buzzer Audio Jack

About This Product

Calling all micro:bit enthusiasts! This Sensor:bit expansion board from ELECFREAKS (they're an official micro:bit partner, by the way) is seriously handy for expanding what your micro:bit can do. It's pretty small at 57mm x 42mm, but it packs in a ton of features. It extends all the available IO ports from your micro:bit and brings them out as GVS pins, which means you can connect all sorts of 3V modules like LED lights, photocells, and various sensors. There's even a built-in buzzer and an audio jack - so you can play music through the buzzer or plug in headphones (which automatically disconnects the buzzer, smart!). It's perfect for classrooms, especially when it's noisy and students need headphones. The board also has a separate IIC port for connecting cool components like OLED displays or BME280 sensors. Oh, and it's got Lego-compatible jacks too, which is awesome for building projects. Each IO port is clearly labeled with silk screening, so you don't have to guess which pin is which. It works with 2.7-3.3V and weighs only 18g. Whether you're a teacher, student, or hobbyist, this board really opens up a world of possibilities for your micro:bit projects. It's one of those accessories that just makes working with micro:bits so much easier and more fun!
