Create schematic of a microcontroller from its dev board // With KiCad, Arduino Zero to SAMD21G
#microcontroller #schematic #prototyping
SAMD21G microcontroller, which is part of the popular Arduino Zero dev board, will be used as an example to extract it out into a separate schematic. How do we go about connecting its pins? We will do pin mapping by checking through many open source schematics and then connect the power, ground, rest, TX/RX LEDs, and the SWD pins.
