Questions
How big is the Grove based board PCB?
It measures 88.6 × 31 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Grove based board use?
103 parts, built around the MMC5983MA-B, VEML6040A3OG, ICM-42688-P and SI1967DH-T1-GE3-VB. 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 Grove based board KiCad files?
From the TomjWolcott/Autonomous-Torpedo repository on GitHub, at the commit this page was made from: the board is torpedo_pcbs/Grove_based_board/Grove_based_board.kicad_pcb and its schematic Powered_Torpedo_V2.1/Powered_Torpedo_V2.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Grove based board design in my own project?
Its repository states no licence, so its author keeps all rights: ask TomjWolcott before reusing the design.
