Questions
How big is the Adapter prototype no uart PCB?
It measures 21.8 × 23.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Adapter prototype no uart use?
22 parts, built around the ESP32-C3-MINI-1-N4, SN65HVD230D and AMS1117-3.3. 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 Adapter prototype no uart KiCad files?
From the UeS5/PCBs repository on GitHub, at the commit this page was made from: the board is hud_project/adapter/adapter_prototype_no_uart/adapter_prototype_no_uart.kicad_pcb and its schematic esp_flasher/esp_flasher.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adapter prototype no uart design in my own project?
Its repository states no licence, so its author keeps all rights: ask UeS5 before reusing the design.
