TVS Diodes, use for example Wurth 82356050050 \nProbably any 5V TVS/ESD suppressor will work\n\nFor added protection input resistors R1 and R2 may\nbe increased to a higher value. In that case one could\nprobably rely on the internat ESD protection in the ATMega.

For use without galvanic separation:\n\n- Do not place U2 and U3 \n- Do not place C5, C6, C8, C9, R9, R10, R11\n- Place R5, R6, R7, R8
