So the piece of scrap copper clad board I drew traces on didn't turn out good at all - when I started scrubbing it with the chloride, the traces smudged away! I relally didn't know that scrubbing it off makes it easier only for toner transfer made PCBs. Nevermind, grabbed myself a protoboard and soldered a few wires to the module I sticked to the border with some tape. Also I made a basic voltage regulator with three 10k resistors so the CC2540 does not get fried from the RX again. Heh. Fried T-Rex.
