Questions
How big is the Esp32 hotplate digital PCB?
It measures 89.1 × 49.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 hotplate digital use?
97 parts, built around the ESP32-WROOM-32, CH340G, MP1470-MS and USBLC6-2SC6. 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 hotplate digital KiCad files?
From the ToLABaki/ESP32-HotPlate repository on GitHub, at the commit this page was made from: the board is hardware/electronics/controller/esp32_hotplate_digital.kicad_pcb and its schematic hardware/electronics/controller/esp32_hotplate_digital.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 hotplate digital design in my own project?
Its repository states no licence, so its author keeps all rights: ask ToLABaki before reusing the design.
