micro:bit IO 擴展板 DFRobot 原廠

micro:bit IO 擴展板 是一個micro: bit的IO口擴展板。該擴展板以Gravity標準接口方式引出micro:bit的所有IO口，帶獨立I2C接口和串口。考慮到蜂鳴器和金手指使用頻率較高，擴展板也額外添加了蜂鳴器和金手指。配備PWR小燈，方便查看通電狀態。引腳色彩分明，方便區分。擴展板背面所有接口及其功能都以絲印標註。該擴展板增大了micro:bit的使用範圍，增強了主板易用性，降低了主控板損耗率。 
本款micro: bit IO口擴展板尤其適用於佔用引腳較多和涉及移動的項目，例如micro: bit小車， micro: bit小機器人等。

This is a micro: bit IO port expansion board. The expansion board uses the Gravity standard interface to extract all IO ports of micro:bit with independent I2C interface and serial port. Considering the higher frequency of buzzer and gold finger use, the expansion board also adds an additional buzzer and gold finger. Equipped with PWR small lights for easy viewing of power-on status. The pins are color-coded for easy differentiation. All interfaces on the back of the expansion board and their functions are marked with silkscreen. The expansion board increases the use range of micro:bit, enhances the usability of the motherboard, and reduces the loss rate of the main control board.
This micro: bit IO port expansion board is especially suitable for projects that take up more pins and involve moving, such as micro: bit car, micro: bit small robot.
