Questions
How big is the Microduino UART PCB?
It measures 25.5 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Microduino UART use?
19 parts, built around the MAX3232ID, BC847B and BSP315PH6327XTSA1. 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 Microduino UART KiCad files?
From the r-map/rmap repository on GitHub, at the commit this page was made from: the board is kicad/stima_v3/Microduino_UART/Microduino_UART.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Microduino UART design in my own project?
Its repository states no licence, so its author keeps all rights: ask r-map before reusing the design.
