Questions
How big is the BaSe PWR V4 0 PCB?
It measures 114.3 × 114 mm and has 4 copper layers, 0.81 mm thick.
What parts does the BaSe PWR V4 0 use?
109 parts, built around the DRV8220DSG, LM2596S-5.0, AMS1117-3.3 and TS0101F020V4. 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 BaSe PWR V4 0 KiCad files?
From the M-Welsch/backup-server repository on GitHub, at the commit this page was made from: the board is hardware/circuit_boards/base_pwr/BaSe_PWR_V4_0.kicad_pcb and its schematic hardware/circuit_boards/base_dc_motor_test/BaSe_DC_Motor_Test_V1_0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BaSe PWR V4 0 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
