We're always striving to improve product quality, so we've upgraded all of our PCBs to a gold-plated ENIG (electroless nickel immersion gold) process. ENIG boards are free from lead and the surface is more even, which facilitates placement of SMT components. Surface oxidation is inhibited (if you take the boards out of their vacuum bags early) and solder bonds readily with the gold surface. Enjoy! :)

After receiving the new final production test case from Hallik Engineering, we quickly fitted all boards and created a new "lefty" v4+, in a new (and maybe more eye-friendly?) color scheme: emerald green! Also, now it finally has printed labels! Enjoy!
