Questions
How big is the HNTemperatureMonitorPCB PCB?
It measures 35 × 30.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HNTemperatureMonitorPCB use?
34 parts, built around the ESP32-S3-MINI-1-N8, ENS210, D3V3XA4B10LP and TLV75801PDRV. 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 HNTemperatureMonitorPCB KiCad files?
From the lyallbeveridge/HNTemperatureMonitor repository on GitHub, at the commit this page was made from: the board is hardware/HNTemperatureMonitorPCB/HNTemperatureMonitorPCB.kicad_pcb and its schematic hardware/HNTemperatureMonitorPCB/HNTemperatureMonitorPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HNTemperatureMonitorPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask lyallbeveridge before reusing the design.
