Pimoroni Zero LiPo Power Board

SKU CH-86KJ-0GJTA

Compact boost board powers a Raspberry Pi from a LiPo cell with up to 1.5 A and 96 % efficiency

  • Compact power for mobile Pi projects using TPS61232 boost converter
  • Up to 96% efficiency extends battery run-time
  • 5A continuous output drives demanding peripherals
  • 15µA quiescent current preserves charge during shutdown
  • 8mm PCB sits flush under Pi Zero, 3, 2, A+, B+

Compact Raspberry Pi Power Board

The Pimoroni Zero LiPo is a 0.8mm thick PCB shaped to sit low on Raspberry Pi 3, 2, Zero, A+ and B+ models. It connects to a LiPo or LiIon battery via a 2-pole JST connector and supplies up to 1.5A continuous current for mobile projects. The kit includes a rubber foot and an optional 2x4 0.1" female header for removable installation.

Efficient Boost Conversion

The board uses a TPS61232 step-up boost converter from Texas Instruments that delivers up to 96% efficiency. Power-on and low-battery indicator LEDs provide visual status feedback. During shutdown caused by undervoltage or external selection the quiescent current drops to just 15uA. This is not a charger; a separate charger such as an Adafruit Micro Lipo or PowerBoost 1000 Charger is required to recharge the battery.

Minimal Build Footprint

Solder the board directly to the GPIO header for a permanent low-profile solution or use the supplied header for a removable option that blocks the GPIO pins. The compact shape frees up space inside tight enclosures while providing reliable battery power. Builders needing integrated charging or higher current delivery will need a different power solution.

Questions about this item

How do I install the Zero LiPo on a Raspberry Pi Zero and what step do people often miss?

Solder the 0.8 mm PCB directly to the GPIO header for a permanent fit, or add the supplied 2×4 0.1" female header for a removable option — remember the header will block the GPIO pins.

What maintenance will the Zero LiPo need over time?

The board is not a charger, so you must use a separate LiPo charger such as the Adafruit Micro Lipo or PowerBoost 1000 Charger to keep the battery topped up.

What limit appears first during sustained use of the Zero LiPo?

The TPS61232 boost converter supplies up to 1.5 A continuous current; exceeding that will trigger the low-battery LED and shut-down protection.
