About the Phase3-backplane PCB

Phase3-backplane is an open source PCB design by udaravima, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 330 × 100 mm, with 28 components from 26 distinct parts.

Other key parts include the INA228AIDGSR. By type, the board carries 18 connectors, 3 capacitors, 3 resistors, 1 IC and 1 diode.

It belongs with the power & battery designs in this gallery.

From the project

A modular, rack-style DC power supply: up to 8 hot-pluggable 600 W buck modules on a shared DC input bus, coordinated by a central manager over CAN. Each channel is a self-contained analog CV/CC supply with bench-grade precision, usable for lab work, bulk DC power, and battery ch

A modular, rack-style DC power supply: up to 8 hot-pluggable 600 W buck modules on a shared DC input bus, coordinated by a central manager over CAN. Each channel is a self-contained analog CV/CC supply with bench-grade precision, usable for lab work, bulk DC power, and battery charging.

- Phase 0 — design docs: complete (01–07). - Phase-1 schematic: complete (v1) and machine-verified — 7 generated sheets, 137 components; every net asserted against the intended net table, every footprint pad-checked; vendor symbols/footprints datasheet-vetted. Audited with the kicad-happy analyzers + ngspice…
