I designed a board that would substitute Arduino Uno and would have an input for a lipo battery to use with the Adafruit 1.44″ Color TFT Breakout Board
after breaking the 1/64” bit on the Othermill I decided to acid etch instead, so just milled the trace and the vias.
and a few failed toner transfers –
After milling the vias and outline on the Othermill, doing the toner transfer and correcting with a black sharpie, this came out of the acid etching.
Some corrections were needed to break connections.
I started populating the board with the parts I had, and waiting on the rest to be able to finish it
