  1. I have managed to break a HF choke between the RK3288 and the ESD5304D in front of the HDMI port. I would like to know choke's part number or if there is a bill of materials that I can use to find the element's make. I could guess it's something like TDK ACM2012H-T05, but my caliper is not good enough to correctly measure the size to be 2.0mm x 1.2mm x 1.2mm. I have seen the reference board schematics for RK3288 and HDMI port there doesn't have chokes and I am wondering if I can use any HF choke with different impedance or even if I can hard cross wire it. PS. I am not very good at electrical engineering. I now a few things, but not that much. Don't judge me too hard, please.
