About
This is a simple PCB implementing the support circuitry necessery to properly connect a Thermistor to an ADC pin.
While originally intended to be used with the SKR Pico's SERVO port to add a port for a chamber thermistor, this board should have universal compatability.
It should be noted that this board uses 0603 SMD components, and as such hand-assembly may be more tricky to novices, though I have made sure to use the enlarged hand-assembly footprints.

Questions
How big is the Panel PCB?
It measures 90.3 × 90.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel use?
755 parts, built around the BLM18KG121TN1D. 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 Panel KiCad files?
From the comradef191/adc2therm repository on GitHub, at the commit this page was made from: the board is KiCad Source/Panelisation/panel.kicad_pcb and its schematic KiCad Source/adc2therm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
