Questions
How big is the Rtl2832u r820t PCB?
It measures 22 × 30 mm and has 6 copper layers, 0.85 mm thick.
What parts does the Rtl2832u r820t use?
75 parts, built around the BFTC-415+, TPS7A2030YCKR, CAT24C04C4ATR and PCA9306YZTR. 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 Rtl2832u r820t KiCad files?
From the taskx6004/rtl-sdr_m2e-minimum repository on GitHub, at the commit this page was made from: the board is rtl2832u-r820t.kicad_pcb and its schematic rtl2832u-r820t.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rtl2832u r820t design in my own project?
Its repository states no licence, so its author keeps all rights: ask taskx6004 before reusing the design.
