<p><strong> ● </strong>模组支持 BT PAN 功能可以直接连接手机上网,相比 WIFI 功耗更低,更加适合电池场景,带屏连接功耗仅 <strong>30mA</strong>。</p>
<p><strong> ● </strong>在本项目中,直接让电池电源直连模组的电源输入引脚 VSYS。这里需要注意,<span style="color:#ff0505"><strong>该模组电压范围要求3.7V~4.7V</strong></span>,不可以使用3.3V 或 5V 供电。</p>
<p><strong> ● </strong>模组的 VDD33_VOUT2 是由软件控制输出的,需要芯片正常启动后才有输出3V3。</p>

<p><strong> ● </strong>音频功放使用 LM4871,是一款 3W、单声道 AB 类音频功率放大器,工作电压 1.9 - 5.5V。</p>
<p><strong> ● </strong>硬件喇叭规格为2415 8Ω1W带线,麦克风咪头为D6*2mm 带线。</p>

<p><strong> ● </strong>本项目通过按键进行控制,SW3 PA34_KEY 是唤醒键 + 语音输入键,按下 SW3 按键可以让主控从低功耗睡眠状态唤醒,当主控正在工作时,按下按键进行语音输入。</p>
<p><strong> ● </strong>主控的IO承受电平是3.3V,而电池电压是最高4.2V,故将按键SW3电路进行分压,当电池电压4.2V时按下按键,IO口电压上拉至3.3V。</p>
<p><strong> ● </strong>SW2为备用设计,暂无功能(后续可能添加)。</p>
<p><strong> ● </strong>指示灯用于指示模组状态。通过模组IO控制。IO输出低电平LED灯亮,IO输出高电平LED灯灭。</p>

<h3 style="line-height:1.8">1. 使用USB转串口连接设备和电脑(设备需接电池)</h3>
<p style="line-height:1.8"><strong> ● </strong>本项目可使用USB转接板连接CH340,TX接SBU2,RX接SBU1(无反应就反过来接,TYPE-C接口正反影响连接顺序),GND连接GND,CH340再连接电脑。</p>
