README.mdrofltemp_1-pcb
This is the circuit schematic and board layout project for the ROFLtemp-1 multi-purpose RTD thermometer.
WARNING! DO NOT BUILD WITH THESE DESIGN FILES! Several stupid errors are in this layout that will be corrected in the final version!
Features:
- High accuracy RTD (PT1000) 4-wire measurement
- Filtering for measurement inputs for high immunity in noisy enviroments (I'm looking at you, induction stoves!)
- USB connectivity for LiPo battery charging, firmware update and data-logging
- High brightness 7-segment LED display for good readability even in daylight
- 0.1° resolution on 3-digit display -> above 99.9 displayed resolution will drop to 1°
- Integrated fast charging, power path management and buck/boost regulator for efficient battery use and continous operation if plugged in

Questions
How big is the ROFLtemp 1 PCB?
It measures 102 × 24.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ROFLtemp 1 use?
225 parts, built around the MAX31865AAP+, BQ24079RGT, TPS63051RMW and DMN1019USN. 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 ROFLtemp 1 KiCad files?
From the washed/rofltemp_1-pcb repository on GitHub, at the commit this page was made from: the board is ROFLtemp_1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ROFLtemp 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask washed before reusing the design.
