USB meter modding - Part 3

The PCB I have ordered from OSH Park arrived.

PCB vs original SOIC-18 microcontroller

The milling wasn't completely perfect, but it is good enough for my needs.  The drill hole is small 0.0197" (0.5mm). One side of the milling was at the mid point of the hole which is the edge of my outline.

Some of the copper were removed by the milling

The goal of the tiny PCB is to replace the hand wired mod.

Hand wired mod vs PCB

I taped down the PCB for soldering/hot air reflow.

I used 3 pieces of "Kapton" tape tohold down the PCB.

It's alive!
