README
board_1.1/README.mdTODO:
- Rearrange MOSFETs so they work as expected
QUESTIONS:
- Do we need the exra pins going to GND on rotary encoder and programing headers if we go for the jumper solution?
FEATURES:
- Fuse for power ports?
DONE:
- Added "0ohm" pull-up between VCC -> CH_PD
- Added 10k pull-up between GPIO2 -> 3.3v
- Added jumper connector to pull-down RESET and GPIO0 -> GND

Questions
How big is the Bitraf hydroponics PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bitraf hydroponics use?
46 parts, built around the ESP-12F, TPS54202DDC and AP2114H-3.3TRG1. 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 Bitraf hydroponics KiCad files?
From the bitraf/bitraf-hydroponics repository on GitHub, at the commit this page was made from: the board is board_1.1/bitraf_hydroponics.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bitraf hydroponics 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).
