Questions
How big is the LPRS1 MAX1000 Shield PCB?
It measures 130 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LPRS1 MAX1000 Shield use?
198 parts, built around the 74HCT244D, LMH6643MM, SA52-11EWA and 74HCT138D. 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 LPRS1 MAX1000 Shield KiCad files?
From the MilosSubotic/LPRS2_Labs repository on GitHub, at the commit this page was made from: the board is HW/LPRS1_MAX1000_Shield_v1.0/LPRS1_MAX1000_Shield/LPRS1_MAX1000_Shield.kicad_pcb and its schematic HW/Ard_Nano_2_LPRS1_MAX1000_Shield/Ard_Nano_2_LPRS1_MAX1000_Shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LPRS1 MAX1000 Shield design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
