PowerPole Power Supply HAT for Raspberry Pi Zero 12-24V

PowerPole Power Supply HAT for Raspberry Pi Zero

Key Features

• Low Ripple Power Supply: Maintains ripple under 15 mV peak-to-peak during high CPU load.
• Stackable Design: GPIO passthrough allows compatibility with additional HATs.
• Optimized Orientation: Downward-facing components provide RF shielding for stacked boards.
• Robust Power Delivery: Accepts 12–24 V input, outputs ±5 V at up to 3 A.
• RF-Optimized Design: Radiated emissions measured below 10 dBuV peak in the 1–500 MHz range.

Compatibility

Tested with and recommended for:

• Raspberry Pi Zero
• Raspberry Pi Zero W
• Raspberry Pi Zero WH
• Raspberry Pi Zero 2 W

For Raspberry Pi 3, 4, or 5 we recommend using the 2023-P-811 board instead for improved current handling.

Performance Testing

Measurements were taken during boot and under CPU load to simulate worst-case power draw.

Ripple & Noise

• Ripple consistently below 15 mVpp.

Radiated Emissions (1 MHz – 500 MHz)

• Measured using a compact TEM cell setup with a 50-ohm load.
• Baseline taken with a lab-grade 5 V supply.
• Compared against the PowerPole HAT mounted on a Pi Zero.

Technical Specifications

• PCB Technology: ENIG finish for durability and conductivity.
• Compliance: RoHS compliant.
• Regulator IC: Based on the LM2596S switching regulator.
• Input Voltage: 12–24 V.
• Output Voltage: ±5 V.
• Maximum Current: 3 A.
• Radiated Emissions: <10 dBuV peak.
