Welcome to the ESPHub-Hardware Wiki!
I intend for this area to be more blog-style, where as I get physical boards made I can document what works with them and what I need to change.
This was the very first board I have ever designed. I ordered 5 fully assembled units through JLCPCB, and out of the box none of them worked as expected.
- 3 boards had 1 or more unsoldered pins on the BH1750 causing them not to be recognized.
- 1 board received no USB power
- 1 board received no USB data
Because none of the boards worked fully, I decided it was time to make the plunge into reflow soldering. I bought a reflow iron and managed to get all 5 boards fully working.
I looked at some breakout boards of the BH1750 and noticed that they made the pads very long, so in my newer designs I extended the solder pads and mask to hopefully promote better adhesion of the IC.
At the time of writing this, I have already incremented up to v0.4. I've added multiple headers, mounting holes in the board, added solder bridge pads, and rearranged some IC/traces. v0.4 is probably the next revision that I will produce as well, as many of the goals I had since v0.1 have been implemented.
