Questions
How big is the Gripper hat PCB?
It measures 65 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gripper hat use?
56 parts, built around the SN74LVC1G125DBVR-TP, SN74LVC1G126DBVR-TP, ADS1015IDGS and TPS54302. 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 Gripper hat KiCad files?
From the nhnifong/stringman-pcbs repository on GitHub, at the commit this page was made from: the board is gripper_hat/gripper_hat/gripper_hat.kicad_pcb and its schematic anchor_hat/anchor_hat/anchor_hat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gripper hat design in my own project?
Its repository states no licence, so its author keeps all rights: ask nhnifong before reusing the design.
