Overview
Controller is an open-source printed circuit board by ieb, from the ieb/windlasscontroller repository on GitHub. It is a 2-layer board of 50 × 102 mm with 9 parts on 18 nets, routed with 110 tracks and 6 vias.
Its parts include 3 switches, 1 resistor, 1 IC, 1 diode and 1 connector.
README
README.mdWindlass Remote Control
I have found that wire windlass switches fail at when installed at the bow due to water ingress into the switches as do sockets. So 7 years ago I used a simple 433Mhz garage door controller as a remote windlass controller. However the remote controls are not easy to use being too small, and the range is typically less than 10m which is shorter than the boat making the controller unreliable.
This project uses a JDY-40 module (typical cost < $1) which can be configured as a remote 8 channel switch. It has a claimed range of 120m, tested at 60m and uses 2.4GHz. It sleeps automatically drawing 5uA when sleeping and requires almost no external components in the controller. The base uses a second JDY-40 module with opto couplers and a G1 transistor driving a relay. Remote is powered by a CR123A 3V lithium battery which should last several years even if left on sleeping. There is an on-off switch. No custom code, but the modules have to be programmed as transmitter and base with the same RF IDs. Code to do this is in setup.
There are 2 schematics, one for base and one for the controller, and designs for the case and base cases.
The PCBs are in KiCad, and were milled using pcb2gcode double sided with alignment, see createGCode.sh for the setup. Everything else is very standard.

Questions
How big is the Controller PCB?
It measures 50 × 102 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
9 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 Controller KiCad files?
From the ieb/windlasscontroller repository on GitHub, at the commit this page was made from: the board is Controller.kicad_pcb and its schematic Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask ieb before reusing the design.
