hey guys, I want to make an usb monitoring system form my dumb ups. So far I've designed the signal sensing and conditioning for voltage (left) and current (right), please let me know I there are mistakes. As mcu I want to use an arduino, is it worth to place an atmega and its ancilliaries on the pcb or should I just place a pro micro clone and call it a day?
