Questions
How big is the Nf tpu PCB?
It measures 44.4 × 58.1 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Nf tpu use?
153 parts, built around the TPS62823DLCT, W25Q128JWSIQ, TPS51200DRC and CR0402-FX-51R0GLF. 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 Nf tpu KiCad files?
From the nf-dj/netforce_tpu repository on GitHub, at the commit this page was made from: the board is boards/nf_art7_100/nf_tpu.kicad_pcb and its schematic boards/nf_art7_100/ddr3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nf tpu design in my own project?
Its repository states no licence, so its author keeps all rights: ask nf-dj before reusing the design.
