Boards in 1 GitHub repository, designed in KiCad, that use the ATTINY441-MU by Microchip Technology (1.7V~5.5V 10bit 12 16MHz 4KB AVR FLASH QFN-20-EP(4x4) Microcontrollers (MCU/MPU/SOC) ROHS). See how each wires it, with its parts, size, README and files; the ATTINY441-MU’s symbol, footprint and pinout are on its own page.
