Inspired by afterearthLTD's reflow plate, but using fewer and simpler, THT components.
Everything is functional but the code only has a curve set up for low-temp solder so far.

Questions
How big is the 50x70 tiny PCB?
It measures 78.3 × 78.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 50x70 tiny use?
23 parts, built around the ATTINY85-15M. 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 50x70 tiny KiCad files?
From the rallekralle11/Tinyreflow repository on GitHub, at the commit this page was made from: the board is 50x70_tiny.kicad_pcb and its schematic 50x70_tiny.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 50x70 tiny design in my own project?
Its repository states no licence, so its author keeps all rights: ask rallekralle11 before reusing the design.
