Usbsupply: common questions
What microcontroller does the Usbsupply use?
The Usbsupply is built around the STM32F030F4, from the STM32 family.
How big is the Usbsupply PCB?
The Usbsupply measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Usbsupply?
78 components, from 46 distinct parts. The full bill of materials is listed on this page.
Where can I download the Usbsupply design files?
From the brightcloudy/usbsupply repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Usbsupply design in my own project?
The repository has no license, so all rights stay with brightcloudy. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Usbsupply without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
