Questions
How big is the Esp32 pelco board PCB?
It measures 213.4 × 88.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 pelco board use?
93 parts, built around the CH340E, ESP32-WROOM-32U, PCA9685PW and ADS1115. 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 pelco board KiCad files?
From the abzman/pelco-kbd300a-replacement-controller repository on GitHub, at the commit this page was made from: the board is board/esp32 pelco board/esp32 pelco board.kicad_pcb and its schematic board/esp32 pelco board/2n7000 buffer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 pelco board design in my own project?
Its repository states no licence, so its author keeps all rights: ask abzman before reusing the design.
