Hi electronic folk! 

I'm writing to you to ask if someone should review the schematics  and the PCB layout of my project. Here the link

As mentioned it is a datalogger for Arduino MEGA 2560 with the goal to measure the temperature and the coolig power of objects that are colder than a certain reference (for example ambient temperature measured by a DHT22). Furthermore, the board include a oled display to show some info and measurements, and a NODEMCU WIFI (ESP8266) to host a web app for remote control and data transfer. More details can be found at the following link https://oshwlab.com/gpplio93s/fresco_giga that reports the story of the first device (multiple boards) and the scope of the scientific work. 

Best regards,

Giuseppe
