DFRobot原廠 micro:bit RGB 全彩LED燈環擴展板 (ROB150)
micro: Circular RGB LED Expansion Board
micro:bit RGB 全彩LED燈環擴展板可以是一個酷炫時鐘，一個定時器；也可以是一個幸運轉盤遊戲機；還可以是一個可穿戴的裝飾；或者是一個互動的彩色裝飾吊墜。
只要裝上micro:bit主板，這個板載了24顆RGB燈的環形燈擴展板就是一個精美的創客互動作品。你可以通過板載的蜂鳴器變身成番茄計時器；通過板載的麥克風，變身成彩色音樂頻譜儀；我們還預留了P0、P1兩個外接端口，通過連接數量龐大的boson及Gravity傳感器，你可以創造出更多有趣的玩法。
通過剪紙、亞克力等製作，你還可以為環形燈環套上各色新裝，中國春節的時候為他帶上紅色中國結，兒童節為他裝扮卡通臉譜，聖誕節為他蓋上雪花或者聖誕樹... ...
This board can be a cool clock, a timer, a Lucky Turntable Game, a wearable ornament, and an interactive colored pendant. With a
micro:bit main board, this 24 RGB LEDs circular expansion board changes to an exquisite creator's piece. You can turn it into a tomato timer via the onboard buzzer, and turn it into a colorful music spectrometer through the onboard microphone; There are two external ports P0, P1 in reserve, so you can get more ways to play by connecting a large number of boson and gravity sensors. With different paper-cuts and acrylics, you can put on a variety of new clothes for the expansion board. For example, put on red Chinese knot for it in Chinese New Year, put on the cartoon face for it at Children's Day, put on the snow or Christmas tree for it at Christmas.
