Questions
How big is the ESP32 DEV MOD PCB?
It measures 39 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 DEV MOD use?
21 parts, built around the LESD5D5.0CT1G and PTVS5V0Z1USKYL. 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 DEV MOD KiCad files?
From the msurendra7095/UART_Bridge_Schematic_PCB_Design repository on GitHub, at the commit this page was made from: the board is ESP32_DEV_MOD.kicad_pcb and its schematic ESP32_DEV_MOD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 DEV MOD design in my own project?
Its repository states no licence, so its author keeps all rights: ask msurendra7095 before reusing the design.
