自从在微博上看到Raspberry Pi的消息后,我一直在观察,这个小东西有可能再一次改变我们的生活,就像当初乔布斯和沃兹创造的奇迹一样。
我是一名芯片制造企业的员工,深知芯片成本,像Raspberry Pi采用ARM 11内核的产品也要卖得这么火热,总觉得哪里怪怪的,于是去网上搜了一下。果然,被我找到了跟我一样想法的人,他们已经做出了一些类似的方案,而且性价比更高。
即表中基于珠海全志公司A10方案的产品,估算成本约为15美元(完全有可能哦),昨天还看到一家深圳企业爆出A10方案的单板售价176RMB的消息,可以去网上搜搜。
A10方案是用在平板电脑上的成熟平台,性能跟RPI比,高下立见。抛砖引玉,欢迎大家万博manbext登录网址!
