Questions
How big is the Breezedude transmitter PCB?
It measures 53 × 22.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Breezedude transmitter use?
59 parts, built around the ATSAMD21G18A-AU, HP203B, D1213A-04TS-7(ES) and STLQ015M33R. 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 Breezedude transmitter KiCad files?
From the Breezedude/breezedudeWindSensor-pcb repository on GitHub, at the commit this page was made from: the board is transmitter/breezedude_transmitter.kicad_pcb and its schematic protection_board/protection_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Breezedude transmitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask Breezedude before reusing the design.
