Automated cat food dispenser PCB

Finally the power supply modules arrived, and I could finish the layout.

And sizes seems to be fine, and with enough clearance too.

My first plan was to just use serial between the ESP8266 and Atmega329P, but I changed that to I2C instead, with a pair of BSS138 for level shifting.

A bit more love to the silkscreen, and it looks like I am ready to order the first prototype. 😉
