Questions
How big is the Stm32h750-expansion PCB?
It measures 48 × 45.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm32h750-expansion use?
73 parts, built around the STM32H750XBH6, AT24MAC402-XHM, ECS-1612MV-250-CN-TR and MI0603J601R-10. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stm32h750-expansion KiCad files?
From the azonenberg/efinix-tests repository on GitHub, at the commit this page was made from: the board is trion-t20-bga256/stm32h750-expansion/pcb/stm32h750-expansion.kicad_pcb and its schematic trion-t20-bga256/rgmii-expansion/rgmii-expansion.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32h750-expansion design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
