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 micro-USB charger uses the MCP73831 and allows you to charge 3.7V LiPo cells at a rate of 100mA max. If you want to charge at a faster rate, you will need to connect a separate power supply to the pins labeled ‘5V’ and ‘GND’ under the label ‘charge’.

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!

  • So, my wife wanted to have some small plants in the house. I didn’t, so we compromised, and got some plants. The only thing is that neither of us remembers to water them, so I wanted to build a sensor array to monitor the moisture content of the soil, and notify us when they needed watering. We’ve got 3 plants, all fairly close to each other, and I wanted to create an IoT project so that it could send an email notifi...

    A lot of the other combo charger/ booster units are bigger than this one - nice match for the 500ma lipo (Posted on 18/09/2016)
