Questions
How big is the FPGAPRO PCB?
It measures 142 × 166.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FPGAPRO use?
257 parts, built around the ESP32-DEVKITC-32E, LM3915, NE5532 and TPS60400QDBVRQ1. 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 FPGAPRO KiCad files?
From the SFMonsun/FPGA-I2S-IIR-Filter-implementation repository on GitHub, at the commit this page was made from: the board is Kicad/FPGAPRO.kicad_pcb and its schematic Kicad/FPGAPRO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FPGAPRO design in my own project?
Its repository states no licence, so its author keeps all rights: ask SFMonsun before reusing the design.
