ESP8266 Irrigation Controller is as hobbyists friendly as possible. It allows to control up to 12 valves driven either by 12v or 24v. ESP can be programmed using Arduino software with built-in USB port. On board WS2812B LEDs are used to indicate valves status. N-Channel MOSFETs are controlled using GPIO Expander (Texas Instruments PCF8575) connected via I2C interface to ESP. Built-in buck regulator supplies 5V to WS2812B LEDs and to LDO powering ESP8266. Lastly two 3pin headers can be used to connect hall-effect water flow sensors to precisely measure the amount of water used to irrigate a garden. I'm myself, hobbyist and mechanical engineer, daily I use Circuit Maker (free CS alternative from Altium) for various projects where I designed Flight Controller for a drone and various other smaller projects. Even though I'm very open source minded person, I'm engaged a lot in startup community and in some cases I need to design some closed source projects which can't be made open source - for this winning Circuit Studio license would help me a lot as I find it much easier to use than KiCad or other free software.
