Raspberry Pi DC Power Board

Industrial-Grade 5V 5A High-Power Supply Board for Raspberry Pi

A rugged, industrial-grade power supply board designed to reliably power the Raspberry Pi 3, Pi 4, Pi 5, and high-draw peripherals. Powered by the high-efficiency TPS54540 buck architecture, this module converts a wide 7.5V to 24V DC input into a stable, continuous 5.2V / 5A output, completely eliminating low-voltage warnings and thermal throttling under heavy computational loads.

It is the ideal solution for demanding setups using attached USB 3.0 SSDs, NVMe HATs, touchscreens, and robotic actuators without triggering system brownouts.

Key Features & Capabilities

• High-Current Output: Delivers 5.0A continuous (6.0A peak) output, satisfying the full power budget of a maxed-out Raspberry Pi 5 alongside high-draw peripherals.
• Wide Input Compatibility (7.5V–24V DC): Integrates seamlessly into 12V automotive systems, 24V industrial automation networks, 3S–6S LiPo battery setups, or standard wall adapters.
• Dual Input Interface:
• 2.1mm x 5.5mm DC Barrel Jack: Fast plug-and-play testing using standard AC adapters.
• 2-Pin Screw Terminal Block: Secure, heavy-gauge wire connections for industrial cabinets, custom enclosures, or mobile builds.
• Optimized Output Voltage (5.2V Target): Factory-tuned feedback network compensates for high-current line losses, ensuring a clean 5.2V reaches the Pi's power pins.
• Advanced Thermal Architecture: Non-synchronous step-down buck topology with dedicated PCB copper pours and thermal vias ensures cool operation under continuous heavy loads without requiring bulky external heatsinks.
• Comprehensive Protection: Onboard Transient Voltage Suppression (TVS diode) clamps voltage spikes and inductive plug-in surges to protect downstream logic.
