3D-printable pinch valve for irrigation and sensor-driven liquid control.
Boards in 4 GitHub repositories, designed in KiCad, that use the ATTINY804-SSN by Microchip Technology (-40℃~+105℃ 1.8V~5.5V 10bit 12 128Byte 20MHz 512Byte 8 Bit 8KB AVR Built-in FLASH SOIC-14 Microcontrollers (MCU/MPU/SOC) ROHS). See how each wires it, with its parts, size, README and files; the ATTINY804-SSN’s symbol, footprint and pinout are on its own page.
