+#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.
+
+Features:
+
+* 0.8mm thick PCB
+* Shaped to sit as low as possible on the Raspberry Pi 3, 2, Zero, A+, B+
+* 2-pole JST connector ideal for most LiPo/LiIon batteries
+* Power and low battery LED indicators
+* Supplies up to 1.5A continuous current
+* Low battery warning at 3.4V (assets GPIO #4 high)
+* Automatic shutdown at 3.0V to protect your battery
+* VBAT+, GND, and EN pins available to break out
+* 15uA quiescent current
