Hi, The only requirement for this schematic is placing c3 and c4 as close as possible to VDD and ground of two ICs. Also, the ground tracks need to be as big as possible so basically a ground plane.I am having a problem to implement this features. So I'd appreciate if you could help me make the PCB as I have no experience in designing PCBs. Kindest regards B https://easyeda.com/editor#id=80ed88fbf58e45dabbd58922da867d3f
