# Zero LiPo
|
||
|
|
|
||
|
|
The Zero LiPo aims to give you the most compact Raspberry Pi power supply possible.
|
||
|
|
|
||
|
|
The board includes power on and battery low indicator LEDs as well as a JST connector, to which you can connect a LiPo, LiIon, or other battery with a JST plug. The TPS61232 step-up boost converter from Texas Instruments converts the 3-4.2V input voltage from the LiPos/LiIons to 5V, providing a stable 5V supply perfect for your Pi.
|
||
|
|
|
||
|
|
To setup the monitoring of the Battery and trigger a clean shutdown when the voltage drop below 3.4V, simply run:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
curl https://get.pimoroni.com/zerolipo | bash
|
||
|
|
```
|
||
