Feel pretty pleased with myself, I just built my first home-designed PCB and it worked :alex_grin:

It’s the small bidirectional amplifier described here: http://w7zoi.net/bidirectional_matched_amplifier.pdf and built by w2aew here https://www.youtube.com/watch?v=7TtKE39TWpI

I made a couple of footprint mistakes but didn’t need any bodge wires! I spent ages messing with KiCad but learned a lot, and have a few ideas for changes. I don’t really have a project in mind, but wanted to build something simple I could use to learn.

A small dark blue printed circuit board resting on an LCD display. The board has SMA connectors on the top left and right and three wires on the left. On the board are two almost identical circuits made of 0603 surface mount components and SOT 23 transistors.
