Arduino portable soldering iron board V3

$2 for 10 PCBs & $6 for stencil: Finally, this board is complete and I have a finished product. I’m so happy with this last version of the portable soldering iron board V3.0. It also has a 3D case now, with great design. I hope you like it too! Help my projects on Patreon : my Q&A page: Canal en Español: ------------------COUPONS-----------------
