Boards using the ATTINY45-20PU

35 boards

Boards in 28 GitHub repositories, designed in KiCad, that use the ATTINY45-20PU by Microchip Technology (-40℃~+85℃ 10bit 2.7V~5.5V 20MHz 256Byte 256Byte 4KB 6 8 Bit AVR Built-in FLASH DIP-8 Microcontrollers (MCU/MPU/SOC) ROHS). See how each wires it, with its parts, size, README and files; the ATTINY45-20PU’s symbol, footprint and pinout are on its own page.
