Questions
How big is the ESP32-Based Power Monitoring System PCB?
It measures 133.3 × 58.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32-Based Power Monitoring System use?
161 parts, built around the ESP32-WROOM-32UE-N4, TPS54331D, LR2512-22R050F4 and QM6006D-VB. 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-Based Power Monitoring System KiCad files?
From the mirjunaid/ESP32-Based-Power-Monitoring-System repository on GitHub, at the commit this page was made from: the board is ESP32-Based-Power-Monitoring-System/ESP32_Based_Power_Monitoring_System/ESP32_Based_Power_Monitoring_System.kicad_pcb and its schematic ESP32-Based-Power-Monitoring-System/ESP32_Based_Power_Monitoring_System/ESP32_Based_Power_Monitoring_System.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-Based Power Monitoring System design in my own project?
Its repository states no licence, so its author keeps all rights: ask mirjunaid before reusing the design.
