The SparkFun Adjustable LiPo Charger is a single-cell lithium polymer (LiPo) and lithium ion battery charger. Because it’s adjustable, this charger will be able to safely charge most of our single-cell batteries with ease. With its onboard charge rate selector, you will be able to set the maximum amount of current to charge your battery from 15mA to 500mA.
Once the board is configured for the battery, you can connect power from either a microUSB cable or the pins below the USB connector labeled GND and INPUT. Once power is connected, you can install a single LiPo battery to one of the three battery connectors, the JST connector, PTH pins marked BATT, or the 2450 coin cell holder on the back of the board. The input voltage for the MCP73831 charger IC is between 3.75V and 6V. To fully charge a LiPo battery, it is recommended to have a voltage of around 5V. The charge IC will regulate the voltage down to safely charge the LiPo battery.
Note: The switches on the Adjustable LiPo Charger come shipped with all the switches in the ON position. Before configuring the board, all the switches should be moved to the OFF position.

SparkFun可調LiPo充電器是單節鋰聚合物(LiPo)和鋰離子電池充電器。因為它是可調節的,這個充電器將能夠安全地充電我們的大部分單節電池容易。通過其板載充電速率選擇器,您可以設置將電池充電的最大電流從15mA調整到500mA。
一旦電路板配置為電池,您可以連接microUSB電纜或標有GND和INPUT的USB連接器下方的引腳。一旦電源連接,您可以將單個LiPo電池安裝到三個電池連接器中的一個,JST連接器,標記為BATT的PTH針腳或電路板背面的2450幣形電池座。 MCP73831充電器IC的輸入電壓為3.75V至6V。要完全充電LiPo電池,建議使用5V電壓。充電IC將調節電壓以對LiPo電池進行安全充電。
注意:可調LiPo充電器上的開關隨附所有開關處於ON位置。在配置電路板之前,所有的開關應該移動到OFF位置。
