Questions
How big is the FORWARD PCB PCB?
It measures 84.9 × 90.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FORWARD PCB use?
54 parts, built around the ESP32-WROOM-32D, LESD5D5.0CT1G, SS8050-G and BAT760-7. 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 FORWARD PCB KiCad files?
From the FORWARD-Walker/FORWARD-PCB repository on GitHub, at the commit this page was made from: the board is FORWARD-MAIN/FORWARD-PCB.kicad_pcb and its schematic FORWARD-CONTROLLER/MotorDriverPCB.kicadBefore_March_14_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FORWARD PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask FORWARD-Walker before reusing the design.
