Questions
How big is the Bleriot rs485 PCB?
It measures 40 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bleriot rs485 use?
21 parts, built around the PAN2110P0AA, ST3485EBDR, RS485 and LM1117MP-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 Bleriot rs485 KiCad files?
From the burgrp/bleriot-rs485 repository on GitHub, at the commit this page was made from: the board is board/bleriot-rs485.kicad_pcb and its schematic board/bleriot-rs485.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bleriot rs485 design in my own project?
Its repository states no licence, so its author keeps all rights: ask burgrp before reusing the design.
