Questions
How big is the ESP32-S3-TLTB Board PCB?
It measures 78 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-S3-TLTB Board use?
29 parts, built around the ESP32-S3-DEVKITC-1-N8, SYN480R and ULN2803A. 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-S3-TLTB Board KiCad files?
From the 53Aries/kicad_library repository on GitHub, at the commit this page was made from: the board is ESP32-S3-TLTB-Board-ULN/ESP32-S3-TLTB-Board.kicad_pcb and its schematic ESP32-S3-TLTB-Board-ULN/ESP32-S3-TLTB-Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-S3-TLTB Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask 53Aries before reusing the design.
