PDNode Baseboard is an open source PCB design by DvidMakesThings: a 6-layer, 203 × 151.8 mm board with 208 components (53 distinct parts). It is built around the TPS51225CRUKR, CD74HC4067QRGYRQ1, TCA9548ARGER, SN74LVC1G97QDCKRQ1 and more. Filed under power & battery.

The PDNode-600 is a professional-grade, 600W USB Power Delivery Unit designed specifically for compact 10-inch rack systems, targeting embedded developers, homelab enthusiasts, test benches, and smart infrastructure. It delivers regulated, high-current power across 8x independent

The PDNode-600 is a professional-grade, 600W USB Power Delivery Unit designed specifically for compact 10-inch rack systems, targeting embedded developers, homelab enthusiasts, test benches, and smart infrastructure. It delivers regulated, high-current power across 8x independent USB-C PD outputs and 4x fixed 5V USB-A outputs.

At the core of the PDNode platform is a centralized industrial-grade 24V/25A power supply, distributing regulated DC to dedicated per-port buck or buck-boost converters. Each USB-C port is managed by an MPQ4242-AEC1 PD controller, enabling clean, autonomous negotiation…
