Portability is a big draw here. The open source soldering station RT1, created by Riccardo Pittini, offers some pretty handy features to boot.
The easy to use and portable soldering station has a simple design that uses an external power adapter with a rating of 12V/5-10A. It can also run on 7-24V batteries. Compatible with Weller RT tips, it has a 1.8” TFT full color LCD screen with two independent channels. It’s fully programmable for preset temperatures ranging from 150-450C. The micro-USB port provides required firmware updates (Arduino Pro Micro 5V 16MHz) and can be used for serial monitoring, parameter tuning and debugging.
