From the project
Hardware, firmware, and host tooling for a modular mini-rack power system.
This customer panel contains six released carrier PCBs and one released backplane-prototype PCB. It measures 163.800 x 237.350 mm and is intended for top-side assembly. The top rail is marked PANEL 35e47c0 on F.SilkS.
This is a historical snapshot. Its old 2 × 2 mm LED model has been removed from the active libraries; use its original source revision for complete historical 3D dependencies. Do not substitute the current side-view LED model in this panel.

Mini Rack Power: 6 Carriers + 1 Backplane Prototype: common questions
What microcontroller does the Mini Rack Power: 6 Carriers + 1 Backplane Prototype use?
The Mini Rack Power: 6 Carriers + 1 Backplane Prototype is built around the STM32C092GCU6, from the STM32 family.
How big is the Mini Rack Power: 6 Carriers + 1 Backplane Prototype PCB?
The Mini Rack Power: 6 Carriers + 1 Backplane Prototype measures 163.8 × 237.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Mini Rack Power: 6 Carriers + 1 Backplane Prototype?
435 components, from 52 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Mini Rack Power: 6 Carriers + 1 Backplane Prototype design files?
From the kquinsland/modular-rack-mount-power-system repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Mini Rack Power: 6 Carriers + 1 Backplane Prototype design in my own project?
The repository has no license, so all rights stay with kquinsland. Use it as a reference, and ask the author before reusing the design.
