Hardware Errata
- USB connector backwards
- Silkscreen overlap on some components
- R21 puts chip in SPI mode... should be DNP'd
I2S format: 16-bit Normal clock (rising edge)
TODO:
- fix hardware errata
- update top level readme with board images and latest hardware config

Questions
How big is the Fm streamer PCB?
It measures 39.4 × 57.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fm streamer use?
61 parts. 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 Fm streamer KiCad files?
From the russery/fm-streamer repository on GitHub, at the commit this page was made from: the board is hardware/fm-streamer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fm streamer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
