The 16340 Uno Shield is able to turn your Arduino Uno into a portable project using 2 16340 batteries. The HAT can charge, discharge, and also has battery protection (overcharge or overdischarge). It only needs one 16340 lithium battery to work, and you can use two 16340 lithium batteries at the same time to get more lasting power. When the battery is low, the board will prompt you to use the micro USB to charge it.
Note: Be careful of "+" and "-", You should follow the direction of "+""-" on the PCB. If you insert the batteries in the incorrect orientation the charging chip will be destroyed. This product does not include 16340 battery.
