ExtraCore RST – cheap, tiny Arduino-compatible board variant
ExtraCore RST is a variant of the tiny Arduino-compatible board ExtraCore (designed by Dustin Andrews), with an on-board tactile reset button. Due to its small form factor and minimal parts count, it can be manufactured very cheaply and tucked away out of site for permanent installations.
This was mainly a practice project for me to learn about modifying schematics and board designs in Eagle, ordering blank PCBs, and hand-assembling SMD components.
