Questions
How big is the STM32 RF PCB?
It measures 39 × 15 mm and has 4 copper layers, 1.58 mm thick.
What parts does the STM32 RF use?
39 parts, built around the STM32L432KBU6, NRF24L01P-R, USBLC6-2SC6 and XC6206P332MR. 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 STM32 RF KiCad files?
From the subashgowtham/STM32_RF_PCB repository on GitHub, at the commit this page was made from: the board is STM32_RF.kicad_pcb and its schematic STM32_RF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 RF design in my own project?
Its repository states no licence, so its author keeps all rights: ask subashgowtham before reusing the design.
