Overview
RtSolder is an open-source printed circuit board by juergen4mueller, from the juergen4mueller/rtSolder repository on GitHub. It is a 2-layer board of 81 × 13 mm with 44 parts on 30 nets, routed with 241 tracks and 83 vias.
It is built around the LMR14050SDDAR, MIC5233-3.3YS and SRP6540-3R3M. Its parts include 17 resistors, 14 capacitors, 5 ICs, 3 connectors and 2 switches. It belongs with the PIC boards of this library.

As I have the full Weller power for business I wanted to have a cheap solution to work with Wellers RT solder tips at home. Small package, a wide input voltage range, simple to use and scaleable power consumption have been targets of my project. Final solution is a microchip PIC controller, reading the temperature signal which is processed by a TLV333 op amp, controlling a step down converter to regulate temperature and also drive the display. Output power is adjustable in 10W steps from 10W to 40W. In 10W mode its also possible to use USB power. For higher power a higher voltage is necessary. Voltage maximum is 30V.

Questions
How big is the RtSolder PCB?
It measures 81 × 13 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RtSolder use?
44 parts, built around the LMR14050SDDAR, MIC5233-3.3YS and SRP6540-3R3M. 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 RtSolder KiCad files?
From the juergen4mueller/rtSolder repository on GitHub, at the commit this page was made from: the board is PCB/rtSolder.kicad_pcb and its schematic PCB/rtSolder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RtSolder design in my own project?
Its repository states no licence, so its author keeps all rights: ask juergen4mueller before reusing the design.
