Questions
How big is the TapeBot PCB?
It measures 99.6 × 101.6 mm and has 4 copper layers, 4.69 mm thick.
What parts does the TapeBot use?
70 parts, built around the TEENSY 4.1, L7805ABD2T-TR and MMBT4403. 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 TapeBot KiCad files?
From the charm-lab/Tapebot-Code repository on GitHub, at the commit this page was made from: the board is TapeBot PCB Files - Spencer/TapeBot.kicad_pcb and its schematic TapeBot PCB Files - Spencer/LoadCells.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TapeBot design in my own project?
Its repository states no licence, so its author keeps all rights: ask charm-lab before reusing the design.
