Questions
How big is the Rp2040-decoder PCB?
It measures 19.6 × 8.6 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Rp2040-decoder use?
51 parts, built around the RP2040, MD9927, MT2492 and W25Q16JVUXIQ. 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 Rp2040-decoder KiCad files?
From the mikesmitty/electronics-projects repository on GitHub, at the commit this page was made from: the board is rp2040-decoder/rp2040-decoder.kicad_pcb and its schematic e24-receiver-board/e24-receiver-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp2040-decoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask mikesmitty before reusing the design.
