Hello, I need a pcb crircuit to load 4 38120s lifepo4 batteries from a 100w-12v solar pannel. the circuit must be able to provide power to two devices (5 v at 2A and 3.3 v at 0.2A) even during the charge. The board must include: - a low discharge protection for the batteries, - a footprint to plug an arduino pro mini and a rtc to open and close the output power depending on the date and the hour, - the mosfet driven by the arduino to open or close the output, - a on/off switch with 3 positions (OFF, ON with arduino control, ON without arduino), - a voltage sensor readed by the arduino I need eagle files gerber files, bom (xls + order ready to pay on Farnell). I need experienced freelancer in this field the work has to be done in 3 to 5 days max
