Micro:Bit 开箱 + 上手视频
Micro:Bit 零基础上手 -- 连载目录
microbit 小板
板子颜值高，体积小，小朋友可以玩，专业人士也可以用，板子硬件是开源的，所有资料都有且开放，板载芯片和传感器很多，价格 145，值不值往下看看就知道了。
双十一在mouser 买的，有活动 175 返 175 ，更超值。现在活动结束了，可以关注 eeboard 活动专区，关注后续活动。
对板子有兴趣也可以关注 mouser 官网链接：www.mouser.cn/ProductDetail/Seee ... JHClbiQ8iARonwyw%3d
或者在 mouser 官网直接搜 microbit。
购买单号：13123209
颜值高，体积小
包装盒，原装英国货
包装背面
侧面，包装就是普普通通纸盒，印刷漂亮
盒子里面一个静电袋，两个说明书
彩色说明书是上手使用手册，白色的是安全手册，22种语言的。应该是全球发行的板子。国际通用。
板子很小，5cm X 4cm
板子另一面
板载芯片，传感器，接口，led 灯，..........
板载设备自己看，值多少钱自己算算，主芯片是nordic nrf51822 蓝牙芯片，usb 接口芯片是 nxp kl26z，还有radio，加速度，磁sensor
