micro:bit Driver Expansion Board 電機驅動擴展板

自micro:bit問世以來,以其簡單實用的編程方式廣受創客,學生和老師的喜愛。其簡潔的設計,配上豐富的管腳資源,賦予了其無限的可能性。此款micro:bit電機驅動擴展板不僅引出了9個micro:bit板載GPIO接口,還搭載了4路電機驅動和8個舵機接口,其中4路電機驅動可複用為2路步進電機驅動。micro:bit電機驅動擴展採用I2C外擴驅動芯片的方式控制電機和舵機,僅佔用I2C兩個管腳,不佔用其他資源,即可完成電機與舵機的雙重控制。採用HR8833電機驅動,最大持續工作電流1.5A,可驅動普通小型馬達和N20微型金屬電機,每一個電機端口還帶有正反轉指示燈,方便識別電機運行方向,非常適用於學生和創客的一些小製作。擴展的GPIO口和舵機接口均採用DFRobot_Gravity標準接口,支持支持數量眾多的模塊和傳感器,舵機接口更是直接與Vin電源相連,增加供電電流便可支持多個舵機同時工作。擴展板支持3.5V~5.5V電源供電,提供DC2.1插頭和接線端子兩種電源接口方式,可直接接3節乾電池盒。產品附帶一根USB轉DC2.1轉接線,可使用充電寶供電,更加經濟環保。

micro:bit Driver Expansion Board

Since the advent of micro:bit, its simple and practical way of programming is widely loved by makers, students and teachers. Its sample design, coupled with a wealth of pin resources, give it infinite possibilities. This expansion board not only leads to 9 micro:bit onboard GPIO interfaces, but also comes with 4-way motor drives and 8 servo interfaces, of which 4-way motor drives can be reused as 2-way stepper motor drives.

Micro:bit Driver Expansion Board adopts I2C external drive chip to control the motor and servo motor, only takes up two I2C pins and can complete the motor and servo dual control without occupying other resources. Using HR8833 motor driver, the maximum continuous operating current is 1.5A, it can drive the ordinary small motor and N20 mini metal motor. Each motor port comes with a positive and negative rotating indicator to identify the motor running direction conveniently, which is very suitable for students and makers to make small projects. Both the extended GPIO and the servo interface use the DFRobot-Gravity standard interface, supporting a large number of modules and sensors. The servo interface is directly connected to the Vin power supply, thus increasing the supply current which can support multiple servos to work at the same time.

This expansion board supports 3.5V to 5.5V power supply. It provides a DC 2.1 plug and a wiring terminal which can be connected directly to three dry battery boxes. It comes with a USB to DC 2.1 adapter cable, which can be powered by power bank and is more economical and environment-friendly.
