Hey soldering kit makers! Struggling with new coin cell regulations and have a pile of PCBs with coin cell battery holder patterns on them? I made a thing for ours that converts them to USB power, maybe it's handy for you. Ship this instead of a CR2032 holder and boom, your kit no longer contains or uses a coin cell, no compliance needed. It's designed for side-slide style holders (SMT or through-hole) and easy to solder.
