+**Introduction**
 SuperMini NRF52840 is a Pro Micro alternative development board that is compatible with Nice! Nano. Its pins are the same as ProMicro, which means it can be used with almost any ProMicro keyboard. The NRF5280 development board has a 3.7V lithium battery interface and a software switch that can cut off the power of the LED. When turned off, the standby power consumption can reach 1mA.

+**Power Supply**
-===== # 电源 =====
+SuperMini NRF52840 supports charging and discharging of 3.7V lithium battery. The charging rate is 100mA during charging, so a 2000mAh battery takes 20 hours to be fully charged.
-SuperMini NRF52840 支持3.7V锂电池充放电，充电时充电率为100mA，因此2000mAh的电池需要20个小时才能充满。
+Recharging Current warnWhen BOOST is connected, the charging current increases from 100ma to 300ma, and it can only be connected when the capacitor capacity is greater than 500mAh (to avoid explosion💥).

-警告
+**External Battery**
-当BOOST连接时，充电电流从100ma增加到300ma，只有当电容容量大于500mAh时才可以连接（避免爆炸💥）。
+If you need an external battery, you only need to connect the + stage of the battery to B+ and the negative stage to B-. The external lithium battery only supports 3.7V and the charging rate is 100mA (a 2000mAh battery takes 20 hours to be fully charged).NoticeWhen welding, please be careful not to short-circuit the positive and negative poles, which may burn the battery and equipment.

-==== # 外接电池 ====
+**External VCC control**
-如果需要外接电池，只需要将电池的+级接入B+,负级接入B-。外接锂电池只支持3.7V，充电率为100mA(2000mAh的电池需要20个小时才能充满).
+hintWhen P0.13 is set to low, the power supply to the 3.3V, VCC pin will be turned off. This is useful for reducing components that use power when idle (e.g. RGB, LEDs).
-注意
+**Bootloader**
-焊接时请注意不要使正负极短路，烧坏电池和设备。
+If you want to enter Bootloder, please short RST to GND twice within 0.5S. Enter Bootloder, connect to the computer via USB, and a storage device called Nice! Nano will be displayed. At this point you can drag in the .uf2 file to burn the program.

-提示
+{{ :developmentboard:qs-nrf52840_v1.2-pcb_footprint.zip |}}
-当P0.13设置为低时，将关闭3.3V 、VCC引脚的电源。这对于减少空闲时使用功率的组件（如RGB、LED）非常有用。

-如果想要进入Bootloder，请在0.5S内短接2次RST到GND。进入Bootloder，通过USB连接电脑，此时会显示一个叫Nice!Nano的存储设备。此时你就可以拖入.uf2文件，来烧录程序。
