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
