Wio Terminal Battery Chassis 鋰電池擴充盒 內置650mAH鋰電池 產品介紹

Wio鋰電池擴充盒是Wio開發板的必備擴展板，因為它為Wio終端提供了外部電源，以增強其便攜性和緊湊性。它具有650mAH可充電鋰聚合物電池，4個Grove模擬/數字端口，個Grove I2C端口和1個Grove UART端口，以及美觀的ABS防護外殼。Wio終端電池機箱的背面也有相同的Raspberry Pi 40引腳兼容GPIO，以提供更多附加組件！

借助Wio終端開發板 + Wio鋰電池擴充盒，您可以輕鬆構建最強大最密集的IoT項目。

特徵：

• 內置650mAh可充電鋰聚合物電池
• USB Type-C充電
• 過流保護
• 打ic模式/打ic保護
• 4個Grove模擬/數字端口
• 1個Grove I2C端口
• 1個Grove UART端口
• 磁鐵隱藏在外殼內，因此可以將其粘貼在白板上！

技術指標：

1. Wio鋰電池擴充盒可由USB TYPE-C型接口或內部電池供電。USB Type-C的最大輸入電流為2A，輸入電壓範圍為4.75V〜5.25V。
2. 內置電池是可充電鋰聚合物電池，容量為650mAh。的電池輸出電壓是3.7V，4.2V用的電池充電的電壓。
3. 電池只能通過USB Type-C接口充電，而不能通過母連接器或Grove接口充電。
4. Wio鋰電池擴充盒的待機電流小於300uA。
5. Wio鋰電池擴充盒通過USB Type-C接口供電時具有過流保護，並且過流保護的電流閾值為2.5A。
6. 當Wio鋰電池擴充盒箱在電池供電模式下短路時，它將進入打cup模式。短路消除後，它將自動返回正常電源模式。

預防措施：

• Wio鋰電池擴充盒本身無法輸出3.3V電壓，只能輸出5V電壓。要輸出3.3V，必須與Wio Terminal一起使用。
• 當Wio鋰電池擴充盒從電池充電模式切換到電池電源模式時，會有1.2s的電壓下降時間。
• 默認情況下，當Wio鋰電池擴充盒未連接到USB Type-C時，由電池供電。插入USB Type-C後，它會自動切換到USB Type-C供電。
• 將Wio鋰電池擴充盒插入USB Type-C時，它將為電池和連接器上的RPI_5V引腳供電。此時，電池將無法供電。如果鋰電池未充滿電，則充電至100％後將停止充電。
