PDNode-PDCard-4242 is an open source STM32 PCB design by DvidMakesThings: a 6-layer, 57.2 × 29.9 mm board with 74 components (39 distinct parts). It is built around the MCP1702T-3302E/CB, MPQ4242GVE-0001-AEC1-P, INA219BIDCNT, 24AA02E-OT 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…
