Questions
How big is the KwartzLab SensorBoard Rev3-Panel PCB?
It measures 185.9 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KwartzLab SensorBoard Rev3-Panel use?
200 parts, built around the ESP32-C3-MINI-1, BME688, SHTC3 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 KwartzLab SensorBoard Rev3-Panel KiCad files?
From the kwartzlab/Environmental-Sensor repository on GitHub, at the commit this page was made from: the board is pcb/kicad/KwartzLab-SensorBoard-Rev3-Panel.kicad_pcb and its schematic pcb/kicad/KwartzLab-SensorBoard-Rev3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KwartzLab SensorBoard Rev3-Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask kwartzlab before reusing the design.
