Questions
How big is the Esp32 sensor node PCB?
It measures 49.9 × 59.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32 sensor node use?
28 parts, built around the MAX3483AEASA+, SPX3819M5-L-3-3 and 2N7002K. 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 Esp32 sensor node KiCad files?
From the wintrmut3/ECE496Hardware repository on GitHub, at the commit this page was made from: the board is esp32_sensor_node_pcb/esp32_sensor_node.kicad_pcb and its schematic esp32_sensor_node_pcb/esp32_sensor_node.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 sensor node design in my own project?
Its repository states no licence, so its author keeps all rights: ask wintrmut3 before reusing the design.
