A slot extension device for JBC soldering stations with only one soldering iron terminal. It is possible to connect:
- 2x soldering iron with the old hirose connector, like the T210 and T245
- 2x soldering iron with the newer binder connector, like the NT115A and AN115A

Questions
How big is the JBC Multitool PCB?
It measures 122 × 93 mm and has 2 copper layers, 1.6 mm thick.
What parts does the JBC Multitool use?
52 parts, built around the ESP32-WROOM-32, IRM-10-5, TLV1117-33DCY and RT314005. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the JBC Multitool KiCad files?
From the Tropaion/JBC_Multitool repository on GitHub, at the commit this page was made from: the board is hardware/JBC_Multitool.kicad_pcb and its schematic hardware/JBC_Multitool.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the JBC Multitool design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
