Questions
How big is the Easun smp telemetry PCB?
It measures 55 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Easun smp telemetry use?
17 parts, built around the ESP32-C3-WROOM-02-H4 and LM1117-3.3. 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 Easun smp telemetry KiCad files?
From the burgrp/easun-smp-telemetry repository on GitHub, at the commit this page was made from: the board is board/easun-smp-telemetry.kicad_pcb and its schematic board/easun-smp-telemetry.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Easun smp telemetry design in my own project?
Its repository states no licence, so its author keeps all rights: ask burgrp before reusing the design.
