  • Leaded solder is recommended - it's easier to work with.
  • Use temperature controller soldering iron set to 330°C (~620°F).
  • Use flux - it really helps solder to flow.
  • Be careful to not melt solder on gold edge connector. You can protect it with kapton tape.

3D printing

  • Print the part with flat surfaces on the build plate.
  • Textured build plate is recommended for nice finish on visible surface.
  • Supports are not needed as long as your settings are optimized for printing overhangs and bridges.
  • You can use many different materials. PLA, PETG or ABS are great choices.

Printing orientation



Some ENC28J60 Mini boards might be wider than others. If your module does not fit, sand down edges of the board with sand paper.

Connect ENC28J60 module to breakout PCB and press it down in the 3D printed case. It might require some fiddling to attach parts together. Do not use excessive force to avoid damaging delicate parts.
