Questions
How big is the STM32 RF Dongle PCB?
It measures 37.3 × 20 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32 RF Dongle use?
39 parts, built around the NRF24L01, 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 Dongle KiCad files?
From the harrydobbs/USB-to-RF-Module repository on GitHub, at the commit this page was made from: the board is hardware/STM32 RF Dongle.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 RF Dongle design in my own project?
Its repository states no licence, so its author keeps all rights: ask harrydobbs before reusing the design.
