Raspberry Pi DC Power Board
A rugged, industrial-grade power supply board designed to reliably power the Raspberry Pi 3, Pi 4, Pi 5, and high-draw peripherals. Featuring a wide 7.5V to 24V DC input range via either a 2.1mm barrel jack or screw terminal block, this module delivers up to 5A continuous output at a stable ~5.2V. Powered by the TPS54540 buck architecture, it eliminates thermal throttling and low-voltage warnings under heavy computational loads.
Designed specifically to tackle the demanding power requirements of modern single-board computers, this power supply module converts a wide input voltage range (7.5V to 24V DC) into a rock-solid 5.2V / 5A continuous output.
It is the ideal solution for powering power-hungry setups, such as the Raspberry Pi 5, Pi 4 with attached USB 3.0 SSDs, NVMe HATs, touchscreens, and robotic actuators without triggering brownouts or low-voltage throttling.
Key Features & Capabilities
High-Current Output: Delivers up to 5A continuous (6A peak) output, fully satisfying the power budget of a maxed-out Raspberry Pi 5 and USB peripherals.
Wide Input Voltage Compatibility (7.5V–24V DC): Flexible input range allows integration into 12V automotive systems, 24V industrial automation networks, 3S/4S/6S LiPo battery packs, or standard wall power adapters.
Dual Input Interface: 2.1mm x 5.5mm DC Barrel Jack: For fast plug-and-play desktop and bench testing using standard AC adapters.
2-Pin Screw Terminal Block: For secure, heavy-gauge wire connections in custom enclosures, industrial cabinets, or mobile setups.
Optimised Output Voltage (5.2V Target): Factory-tuned feedback network compensates for high-current voltage drops across USB cables, delivering a clean 5.2V directly to the Pi's VBUS/power pins to ensure system stability.
Advanced Thermal Architecture: Powered by a non-synchronous buck topology (TI TPS54540 family) with dedicated PCB ground copper pours and thermal vias, ensuring cool operation even at high continuous loads without needing bulky external heatsinks.
Comprehensive Protection: Integrated transient voltage suppression (TVS diode) at the input clamps voltage spikes and inductive plug-in surges to shield downstream electronics.
Ideal Applications
Raspberry Pi 5 & 4 Power Systems: Eliminate "under-voltage" warnings when running demanding AI models, video processing, or compiling software.
Robotics & Drones: Power a companion computer directly from a 3S–6S onboard LiPo battery pack.
Industrial & Home Automation: Drop existing 12V or 24V DIN-rail control lines down to a clean 5V logic rail.
Custom Enclosures & Kiosks: Use screw terminals for permanent wiring while keeping the barrel jack available for maintenance and debugging.
