Overview
Dimmer is an open-source printed circuit board by kiall, from the kiall/esp8266-dimmer repository on GitHub. It is a 2-layer board of 60 × 60 mm with 29 parts on 35 nets, routed with 165 tracks and 15 vias.
It is built around the BT136X-600,127 and MOC3021M. Its parts include 11 resistors, 4 connectors, 3 capacitors, 3 ICs and 3 diodes. It belongs with the ESP8266 boards of this library.

Revision History:
v1.2:
v1.2 is tested as working.
Fixes:
- Fix PSU Ordering - Secondary DC + and - pins swapped.
- U3 pad size corrected
- C3 470uF footprint corrected
- Add 3v3 + GND power inputs for programming without a mains connection
- PCB Layout reworked
Issues Not Yet Fixed:
- More space behind D1 (Triac) would be better, to allow for a larger heatsink.
- 3v3 + GND power inputs for programming without a mains connection should be labeled on the board.
v1.1:
Fixes:
- Fix Traic Pin Ordering
Issues Not Yet Fixed:
- None

Questions
How big is the Dimmer PCB?
It measures 60 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dimmer use?
29 parts, built around the BT136X-600,127 and MOC3021M. 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 Dimmer KiCad files?
From the kiall/esp8266-dimmer repository on GitHub, at the commit this page was made from: the board is kicad/dimmer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dimmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask kiall before reusing the design.
