The PowerCell board is a single cell LiPo boost converter (to 3.3V and 5V) and micro-USB charger in one. The board comes with a JST connector for a single cell LiPo battery, a micro-USB connector for the 5V charge input, and selectable 3.3V and 5V output pins (labeled ‘out’). There are also two charge pins broken out (labeled ‘charge’), so you can use another 5V power source to charge the batteries, if you don’t have a micro-USB cable.

We’ve also broken out the power-save and enable pins, so that you can have full control of the switching regulator. Keep in mind, if you keep your battery connected to the Powercell, it is recommended that you disable the switching regulator (pull EN low) in order to prevent the battery from discharging and reaching the under voltage cutoff on the battery itself. There is also an under-voltage lockout on the Powercell board which is tied to a solder jumper so that you can disable it if you like.

The boost converter is based on the TPS61200 from TI and has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V (which can be disabled via solder jumper on the back of the PCB).

Note: This board does not have reverse polarity protection, so please be sure to recognize the polarity of your connections!

Note: When you are finished charging your battery, it is recommended that you remove the battery from the Powercell, since the charge will slowly drain without proper management. Check out the Hookup Guide in the Documents section below to learn how to control the charging and regulator output.

在生命之丸板是一種單細胞鋰聚合物電池升壓轉換器（以3.3V和5V）在一個和微型USB充電器。該主板配備了一個JST連接器為單細胞鋰聚合物電池，為5V充電輸入一個微型USB接口，和可選的3.3V和5V輸出引腳（標有“出”）。也有兩個充電引腳爆發（標有“收費”），所以你可以使用另一個5V電源來為電池充電，如果你沒有一個微型USB電纜。

我們還爆發了省電和使能引腳，這樣就可以有開關穩壓器的完全控制。請記住，如果你保持你的電池連接到POWERCELL，建議您禁用開關穩壓器，以防止電池放電，達到對電池本身欠壓截止（EN拉低）。還有對生命之丸板，綁到焊料跳線，這樣，如果你喜歡，你可以禁用它的欠壓閉鎖。

升壓轉換器是基於TI的TPS61200支持，並具有焊料跳線選擇5V和3.3V輸出，以及2.6V的低電壓保護（可通過跳線焊在PCB的背面被禁用）。

注：此板不具有反接保護，所以請一定要認清你的連接的極性！

注意：當您完成您的電池充電，建議您刪除從POWERCELL電池，由於電荷會慢慢沒有適當的管理瀝乾。退房聯播指南中的文檔部分下面來學習如何控制充電和穩壓器的輸出。
