Questions
How big is the Temperature Monitoring Dev Board PCB?
It measures 78.1 × 61.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Temperature Monitoring Dev Board use?
73 parts, built around the STM32F107RCT6, SPX3819M5-L-3-3, PESD3V3L1BA,115 and AO3401A. 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 Temperature Monitoring Dev Board KiCad files?
From the tsokomalusi/Temperature-Dev-Board repository on GitHub, at the commit this page was made from: the board is Temperature_Monitoring_Dev_Board.kicad_pcb and its schematic Temperature_Monitoring_Dev_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temperature Monitoring Dev Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask tsokomalusi before reusing the design.
