Boards in 2 GitHub repositories, designed in KiCad, that use the ATMEGA88PB-AU by Microchip Technology (-40℃~+85℃ 1.8V~5.5V 10bit 1KB 20MHz 27 512Byte 8 Bit 8KB AVR Built-in FLASH TQFP-32(7x7) Microcontrollers (MCU/MPU/SOC) ROHS). See how each wires it, with its parts, size, README and files; the ATMEGA88PB-AU’s symbol, footprint and pinout are on its own page.
