Questions
How big is the SensorBoard PCB?
It measures 23 × 23 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SensorBoard use?
14 parts, built around the LTR-303ALS-01, SHTC3, MCP1700T-3302E/TT(MS) and BZV55B5V6. 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 SensorBoard KiCad files?
From the neerajadsul/SmartSystems repository on GitHub, at the commit this page was made from: the board is SensorNetwork/SensorBoard/SensorBoard.kicad_pcb and its schematic SensorNetwork/SensorBoard/SensorBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SensorBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask neerajadsul before reusing the design.
