<div class="document"> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">哈哈哈哈,我终于设计出来了</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">采用双主控的esp32 pico d4 加上ci1103,虽然pico可以语音识别,但是需要联网,还占用资源,所以采用两块芯片</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">传感器有地磁,加速度,心跳,血氧,(温湿度,和实时时钟,因为放不下了删掉了)等等</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">pico方案来自乐鑫的pdf,ci1103方案来自于官方pdf</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">这是我第一次画四层板,顶板还可以,底板时间仓促,感觉画的不太好</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">mic方案改用了mems,功放选自默认ab类功放,想用d类,不知道怎么改</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">喇叭不想用太响亮的,是8欧 0.5w的</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">我没系统学过四层板,请轻喷</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">!!!!!!!!!!!!重要!!!!!!!!!!!!!!!</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">因为模拟电源和数字电源没有分开命名,所以在0欧隔离处会有报警,有些pin为了直观标了两个网络,会报警告,请忽视</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">PCB因为一次画了两张版,用fpc连接,fpc脚位无直接连接会报警,请忽视</p> </div>
