Questions
How big is the MCU stm32L05 PCB?
It measures 37 × 32 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MCU stm32L05 use?
30 parts, built around the AP2210K-3.3TRG1. 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 MCU stm32L05 KiCad files?
From the m0in92/common_pcb_circuits repository on GitHub, at the commit this page was made from: the board is MCU_stm32L05/MCU_stm32L05.kicad_pcb and its schematic MCU_ATMEGA328p_minimum/MCU_ATMEGA328p_minimum.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MCU stm32L05 design in my own project?
Its repository states no licence, so its author keeps all rights: ask m0in92 before reusing the design.
